[Zope3-checkins] CVS: Zope3/lib/python/ZODB - Connection.py:1.87 TmpStore.py:1.11 utils.py:1.15

[Jeremy Hylton]

Update of /cvs-repository/Zope3/lib/python/ZODB
In directory cvs.zope.org:/tmp/cvs-serv12174

Modified Files:
	Connection.py TmpStore.py utils.py 
Log Message:
Move Set class to utils and use 2.3 Set when possible.

Make sure that TmpStore always has an _created attribute.  I found a
case where this wasn't true when debugging a different failure.  No
time to write a separate test; I'd blow my stack.
