Conversation
Install a SIGALRM handler in clean_exit that aborts when the exit alarm fires, gated on new tunable gbl_abort_on_stalled_exit (default on). Replaces the NDEBUG-only call_abort handler. Signed-off-by: Mark Hannum <mhannum@bloomberg.net>

clean_exitcurrently just dies on the default SIGALRM disposition (or aborts only in debug builds), leaving nothing to diagnose. This installs a SIGALRM handler inclean_exitthat logs and aborts, so the exit alarm produces a corefile showing what we were stuck on. Gated on new tunableabort_on_stalled_exit(gbl_abort_on_stalled_exit), default on. Only the clean-exit path is affected; the bdb watchdog path is unchanged.
