I could never got a core dump for this but after adding ap_log_error()
calls to threaded.c and fprintf()+fflush() calls to APR I found that
sigwait() is segfaulting.

In a run I just did, we had processes sitting happily in sigwait() for
10-11 seconds before they segfaulted.  In another run it happened
within a second.

I can't seem to get strace running on such a process when it segfaults.
