Thanks Graham,

I'll remember the users list in the future. as I was using the trunk, I 
thought it might have been a recent patch to apr/httpd which has caused

BTW.. the acceptmutex works for stock apache, but not for mod_python 
which doesn't have the ability to change the mutex mechanism it uses.
