---------------------------------------------------------------
Attaching derby-5448-02-aa-backoutDocsChanges.diff. This patch removes the 10.8
documentation of the derby.language.sequence.preallocator property. Committed
to the 10.8 docs branch at subversion revision 1179759.
This patch backs out the following commit:
DERBY-5307 1141651: This commit ported documentation of the
derby.language.sequence.preallocator property from 10.9 docs to 10.8 docs. Note
that the property still has meaning for sequences although the property would
be less capable after backing out 1141645.

> New errors were seen while running NsTest against the 10.8.2 release
> candidates. These errors are recorded as DERBY-5430 and DERBY-5422. The first
> error is a deadlock which occurs when inserting into the main table of the
> test. The second error is a problem clearing the identity cache. These errors
> have caused people to lose confidence in the concurrency improvements
> introduced by DERBY-4437. We should back the DERBY-4437 changes out of the
> 10.8 branch and use the trunk to continue debugging the problems disclosed by
> NsTest.
