+commit d654795bb763b95d14604b9b65d09ae79b8ee5b6
+Author: Alex Gorrod <alexg@wiredtiger.com>
+Date:   Mon Mar 9 05:35:33 2015 +0000
+
+    Add a test case for checkpoint consistency.
+    
+    We recently fixed a bug where updating a page after the write leaves phase of a checkpoint had completed, then either checkpointed again or closed the database. We would end up with inconsistent data. That was the case because we weren't marking trees dirty all the time.
+    
+    This test case reproduces the scenario so we don't reintroduce the failure.

+
+    Don't allow LSM bloom create to block waiting for space in the cache.
+    
+    We are only accessing one page at a time, and allowing the bloom create to block can lead to LSM not making progress.

+commit 5285b768de3237b4379f1526176efdeb55860971

+Date:   Thu Mar 5 16:15:08 2015 +1100
+
+    Remove the special "discard" path for trees marked clean: always go through eviction, which checks page modify flags.  This may mean additional writes to internal pages when discarding a tree, but means that if a discard stops part-way through, the remaining in-memory tree has not lost any context.

+
+    If a page is split by eviction, mark the tree dirty to avoid having dirty pages in a tree marked clean.

+Date:   Mon Mar 2 14:18:37 2015 +1100
+
+    Allow memory_page_max to be at most 1/4 of the cache size not 1/2.
+    
+    If we let a single page grow to half the cache size, it's too easy for the cache to get pinned full if it is tiny to start with.

+
+    Several optimizations to large page eviction:
+    
+    * Don't update the read generation on page in if it's set to oldest.
+    * Clear the walk positions before the eviction server sleeps.
+    * If only looking for pages that would block add them all to the queue.
+    * If evicting dirty pages use the worker threads, not the server.

+    Fix a bug in checkpoint, where it could get an EBUSY return.
+    
+    The case that could return EBUSY was when checkpointing with a specific target, while that target was open exclusively or for a bulk load.

+
+    Handle the case where a large record pushes us over a page boundary and we spill across two pages correctly.  The previous fix could let us span additional space.
+    
+    Fix another bug in the fixup code - ensure there is enough space in the temporary buffer when fixing up after the fist page is full.

+
+    Turn off key prefix-compression and rebuild the key before doing the boundary split. The size of the key is likely to increase by a few bytes, and if the value is large enough to consume almost all of the buffer, we overflow the space available.

+
+    Fix a bug in reconciliation.  In cases where we decide to squeeze one more large entry onto a page, we could have attempted to decrement space available negative.

+Date:   Tue Feb 10 12:46:04 2015 -0500
+
+    Sasha says (my paraphrasing): I simply rearranged the fields in the WT_PAGE struct, so that u.row.d and u.row.entries are close together at the very end of the definition of union u, and the "uint8_t type;" immediately follows that.
