A patch posted here may get lost, especially if it's
not simple and obvious enough for instant review and
understanding.  Posting it as an Enhancement request
in Bugzilla would leave a record of it.

If a threaded MPM really isn't an option (for most users the
obvious solution), then the question is what works for you.

Unlikely it would get in to a future 2.2 release unless it
fixed something much more than an arcane performance problem
(arcane because because it only happens when you reject
conventional ways to boost performance, like another MPM). 

How well does your patch apply to trunk?

If you don't want to go in that direction, you could
post somewhere always available for anyone interested.
Our bugzilla would serve, as would somewhere else you
publish from, like github or a personal site.
