--------------------------------------

@Brian Dickinson: Are you checking Cayenne sources via GitHub ? It is certainly in SVN. I
am not sure about Git synchronization policies of Apache repos though.

> I've encountered a deadlock issue in production in an app performing many INSERTs.  The
deadlock was between the PK generator and the PoolManager (getting a DB connection).  It is
very bad.  I added a unit test demonstrating the problem and a fix for it.
> The fix is possibly not ideal because it requires a larger data structure for holding
the cached primary keys, but it is far better than the previous behavior.
> If this fix is acceptable this should be back-ported to 3.1 as well.
