[Zodb-checkins] CVS: StandaloneZODB/ZODB - FileStorage.py:1.63

[Jeremy Hylton]

Update of /cvs-repository/StandaloneZODB/ZODB
In directory cvs.zope.org:/tmp/cvs-serv27084

Modified Files:
	FileStorage.py 
Log Message:
Use os.remove() in all cases, instead of mixing remove() and unlink().

Add one case where failure to remove is not a fatal error. And be more
specific about the error that is caught -- OSError only.
