If we have veto(), it should probably expect a string argument that

I think the time would be better spent fixing ZODB to not allow a
transaction commit after a non-resolvable conflict error is raised.
Then bare except clauses would still be bad style, but not quite as
dangerous.
It'd be nice to add a test to the ZODB test suite that exposes the bug
so we can pro
Could this be done by initializing a dictionary at startup keyed on
thread-id that a ConflictError exception's __init__ could stick a marker
into, then checking that dictionary at commit time and disallowing the
commit if the marker still existed?
