Nobody cares much about the "regexp/threads bug": say, the current thread
implemenation can go away any moment.  There is, however, another bug
of which what you call a regexp/threads bug is just a particular
case.  If you would fix *this* bug, it would be a completely different
topic, and I would spend much more time helping you and making things
perform better.

Even if not your questionable concentration on a thread issue, bug fix
should be optimal wrt performance.  What I see might have been good
for a zeroth approximation, but not much more than that.
