You're right - I get exactly the same sympton on "apachectl restart"
now. It sure isn't hanging - it vanishes without a trace. hmmmm, I've
been the only one breaking^H^H^H^H^H^H^H^H putting good stuff into
threaded lately, so I must have done it somehow.
After adding many ap_log_errors, looks like things go normally until we
hit the code in ap_mpm_run responsible for graceless restart. Then it
sure looks like the parent catches a SIGTERM that it intended to send
the children in ap_start_shutdown (the normal SIGTERM handler).
I'm going to try strace on the parent (thanks Jeff!), and/or backing
out/further scrutinizing my last patch to threaded.
