It may lack the automatic retrieal on "OperationalError"
implemented by other DA's.

Note, that in general it is a bad thing to automatically retry
an operation after an "OperationalError". It may give you
a partial transaction.

The better solution (than retrying the request) is to close/reopen
the connection and then raise a "ConflictError". Zope will
in this case retries the complete request.
