Update of /cvs-repository/ZODB3/BDBStorage
In directory cvs.zope.org:/tmp/cvs-serv27251

Modified Files:
      Tag: ZODB3-3_2-branch
	BDBFullStorage.py 
Log Message:
Explain why it is okay to ignore DBNotFoundError in the pickles table.

This still doesn't explain why catching the error and calling
txn.abort() will cause a DBRunRecoveryError.
