Revision history for Perl extension Genezzo::Contrib::Clustered.
0.24  Sat Dec 24 01:00:00 2005
	Modified DLM code to raise DEADLOCK error on deadlock.
	Added experimental Kngz_Execute hook to catch DEADLOCK.
	Modified DLM code to support demoteAll (to SH) besides unlockAll.
	Commit now uses demoteAll insead of unlockAll, to match current
	  buffer cache behavior.
	Added DLM function ast_poll to determine whether there are any
	  recent requests for locks held by that process.
	Added new client genloopclient.pl to test locking interactions between 
	  clients. 
	Now recommend rollback as first action in gendba or scripts,
	  so all blocks will be locked.

0.23  Fri Dec 23 12:00:00 2005
	Modify ReadBlock to replace instead of wrap _filereadblock
	  to avoid duplicate reads.
	Attempted moving DirtyBlock to BufCaElt::_dirty; doesn't work
	  so left old DirtyScalar::STORE method registered.
	sync is no longer called on non-Cygwin Win32.  autoflush(1) is
	  called instead.  Yes, this probably gives terrible performance,
	  but it should pass CPAN Testers :-)
