Update of /cvs-repository/ZODB4/Persistence
In directory cvs.zope.org:/tmp/cvs-serv19984/Persistence

Modified Files:
	cPersistence.c 
Log Message:
Free the __dict__ of a ghost.

This is a simple change that seems to have been delayed for no good
reason.  It could lead to perplexing crashes, however.  I've tested on
a couple of Python versions, bu not on Windows.  We should be a little
suspicious of this change until it's seen more testing.
