bigfile001
	Create a database greater than 4 GB in size.  Close, verify.
	Grow the database somewhat.  Close, reverify.  Lather, rinse,
	repeat.  Since it will not work on all systems, this test is
	not run by default.

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
bigfile002
	This one should be faster and not require so much disk space,
	although it doesn't test as extensively.  Create an mpool file
	with 1K pages.  Dirty page 6000000.  Sync.

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

	Then reopen the file, re-retrieve everything.  Finally, delete
	everything.

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
dead001

	Same test as dead001, but use "detect on every collision" instead
	of separate deadlock detector.

	create a database in that directory.

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

	Run with region overwrite flag.

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
jointest
	Test duplicate assisted joins.  Executes 1, 2, 3 and 4-way joins
	with differing index orders and selectivity.

	We'll test 2-way, 3-way, and 4-way joins and figure that if those
	work, everything else does as well.  We'll create test databases
	called join1.db, join2.db, join3.db, and join4.db.  The number on
	the database describes the duplication -- duplicates are of the
	form 0, N, 2N, 3N, ...  where N is the number of the database.
	Primary.db is the primary database, and null.db is the database
	that has no matching duplicates.

	We should test this on all btrees, all hash, and a combination thereof

recd001
	Per-operation recovery tests for non-duplicate, non-split
	messages.  Makes sure that we exercise redo, undo, and do-nothing
	condition.  Any test that appears with the message (change state)
	indicates that we've already run the particular test, but we are
	running it again so that we can change the state of the data base
	to prepare for the next test (this applies to all other recovery
	tests as well).

	These are the most basic recovery tests.  We do individual recovery
	tests for each operation in the access method interface.  First we
	create a file and capture the state of the database (i.e., we copy
	it.  Then we run a transaction containing a single operation.  In
	one test, we abort the transaction and compare the outcome to the
	original copy of the file.  In the second test, we restore the
	original copy of the database and then run recovery and compare
	this against the actual database.

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

recd003
	Duplicate recovery tests.  For every known duplicate log message,
	makes sure that we exercise redo, undo, and do-nothing condition.

	sure that we exercise all possible recovery actions: redo, undo, undo
	but no fix necessary and redo but no fix necessary.

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
recd004
	Big key test where big key gets elevated to internal page.

recd006
	Nested transactions.

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
recd007
	File create/delete tests.

	This is a recovery test for create/delete of databases.  We have
	hooks in the database so that we can abort the process at various
	points and make sure that the transaction doesn't commit.  We
	then need to recover and make sure the file is correctly existing
	or not, as the case may be.

	DB_FIRST flag and then DB_NEXT.

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
recd016
	This is a recovery test for testing running recovery while
	recovery is already running.  While bad things may or may not
	happen, if recovery is then run properly, things should be correct.

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
recd017
	Test recovery and security.  This is basically a watered
	down version of recd001 just to verify that encrypted environments

rep004
	Test of DB_REP_LOGSONLY.

	There are N different scenarios to tests:
	1. No duplicates.  Cursor A deletes a key, do a  GET for the key.
	2. No duplicates.  Cursor is positioned right before key K, Delete K,
	do a next on the cursor.
	3. No duplicates.  Cursor is positioned on key K, do a regular delete
	of K, do a current get on K.
	4. Repeat 3 but do a next instead of current.
	5. Duplicates. Cursor A is on the first item of a duplicate set, A
	does a delete.  Then we do a non-cursor get.
	6. Duplicates.  Cursor A is in a duplicate set and deletes the item.
	do a delete of the entire Key. Test cursor current.
	7. Continue last test and try cursor next.
	8. Duplicates.  Cursor A is in a duplicate set and deletes the item.
	Cursor B is in the same duplicate set and deletes a different item.
	Verify that the cursor is in the right place.
	9. Cursors A and B are in the place in the same duplicate set.  A
	deletes its item.  Do current on B.

	Test of DB_CURRENT partial puts onto almost empty duplicate

	Test of DB_CURRENT partial puts on almost-empty duplicate pages.
	This test was written to address the following issue, #2 in the
	list of issues relating to bug #0820:

	2. DBcursor->put, DB_CURRENT flag, off-page duplicates, hash and btree:
	In Btree, the DB_CURRENT overwrite of off-page duplicate records
	first deletes the record and then puts the new one -- this could
	be a problem if the removal of the record causes a reverse split.
	Suggested solution is to acquire a cursor to lock down the current
	record, put a new record after that record, and then delete using
	the held cursor.

	It also tests the following, #5 in the same list of issues:
	5. DBcursor->put, DB_AFTER/DB_BEFORE/DB_CURRENT flags, DB_DBT_PARTIAL
	set, duplicate comparison routine specified.
	The partial change does not change how data items sort, but the
	record to be put isn't built yet, and that record supplied is the
	one that's checked for ordering compatibility.
