So as I understand it, there is a bug regarding a race condition in mod_proxy
that is still causing this error.  And the only patch in place is the one above
in comment #82, which I noticed is also in trunk.  However, this patch, while
perhaps a good one to have in place, doesn't solve the race condition.  And the
race condition is the real issue here.

This is a serious problem that is affecting the use of Apache 2.2.8 on many
customers.  The frequency of the error with some sites is high enough that it
puts Apache mod_proxy in jeopardy of being unusable, especially for
non-idempotent requests.  It may be less than 5% of requests at most but that
is a lot for a major traffic site.

Are there any new developments on getting this race condition fixed?

Can someone please point me to the area in the code where this race condition
exists and describe the complications around it that have prevented it from
being fixed thus far?
