While we're discussing this: the current coding with
AbortOutOfAnyTransaction within ProcessInterrupts is *utterly* unsafe.
I realize that's just a toy placeholder, but getting rid of it has to be
on the list of stop-ship items. Right at the moment I'd prefer to see
CONFLICT_MODE_ERROR always turned into CONFLICT_MODE_FATAL than to
imagine this is going to work.
