Update of /cvs-repository/ZODB3/Persistence
In directory cvs.zope.org:/tmp/cvs-serv20567/Persistence

Modified Files:
      Tag: zodb33-devel-branch
	cPersistence.c 
Log Message:
Per_getattro(), Per_setattro():  repaired obvious leaks on almost all
early-exit paths.  What isn't completely clear to me yet is why
checkPackWhileWriting triggered a leak in Per_getattro whenever
a ClientThread sufferred a ConlictError.
