yep

chunk_free()
free()
cleanup_cache_object()
decrement_refcount()
run_cleanups()
apr_pool_destroy()
ap_process_http_connection()
ap_run_process_connection()
process_socket()
worker_thread()

interestingly, I'm not getting the "exit signal" message in
httpd.conf; the crashing thread has left its core.PID but it is a
zombie

so far after applying your patch I haven't hit a problem, though I'm
still waiting on segfaults just in case

I find the possible need for the patch very disturbing; it implies to
me a problem in the atomics code
