-DBPool.py
-
-Implements a pool of cached connections to a database. This should result in
-a speedup for persistent apps. The pool of connections is threadsafe
-regardless of whether the DB API module question in general has a
-threadsafety of 1 or 2.
-
-For more information on the DB API, see:
-	http://www.python.org/topics/database/DatabaseAPI-2.0.html
-
-The idea behind DBPool is that it's completely seamless, so once you have
-established your connection, use it just as you would any other DB-API
-compliant module. For example:
-
-	dbPool = DBPool(MySQLdb, 5, host=xxx, user=xxx, ...)
-	db = dbPool.getConnection()
-
-Now use "db" exactly as if it were a MySQLdb connection. It's really
-just a proxy class.
-
-db.close() will return the connection to the pool, not actually
-close it. This is so your existing code works nicely.

-FUTURE
-
-* If in the presence of WebKit, register ourselves as a Can.

-CREDIT
-
-* Contributed by Dan Green
-* thread safety bug found by Tom Schwaller
-* Fixes by Geoff Talvola (thread safety in _threadsafe_getConnection()).
-* Clean up by Chuck Esterbrook.
-* Fix unthreadsafe functions which were leaking, Jay Love
-* Eli Green's webware-discuss comments were lifted for additional docs.
