what you should realize is that had we applied your previous patch in a
rush, it would have introduced a far more serious regression than the
type of problem you are trying to solve. That's one of the reasons why
we disagree with your sense of urgency.

We've got the clean fixes queued up and it's all under testing. (going
fine so far)

Also, you only appear to have resent your fix with the obvious bug
fixed, but it's still unclean and you do not seem to have replied to my
main structural argument:
