pthread accept mutex not recovered after holder segfaults

Wanted to add that I had what appears to be the same issue with 2.0.47 using the
worker MOM and the pthread AcceptMutex on SGI Irix.  One of the workers took a
SIGBUS which left the other two workers sitting around.  Apache was accepting
requests, but was not responding.  I'm guessing the SIGBUS happened because the
webserver is running a NFS server and has a client nearly constantly writing
files which Apache2 serves up and EnableMMAP was turned on.  I have seen similar
SIGBUSs using Apache 1 but of course functionality was not affected.  I will
also give the sysvsem AcceptMutex a shot and go back to the worker MPM.

Glenn, have you had any more issues with the server hanging when a worker dies
since switching AcceptMutexes?
