I think you should have a trailing \n when writing to stderr.
Here's that reproducer I speculated about (sorry I confused SIGQUIT
and SIGTERM in my earlier email, ENOCOFFEE). Seems to do the job, and
I tested on a Linux box for good measure. If you comment out the
kill(), "check PROVE_TESTS=t/002_archiving.pl" works fine
(demonstrating that that definition of system() works fine). With the
kill(), it reliably reaches 'TRAP: failed Assert("latch->owner_pid ==
MyProcPid")' without your patch, and with your patch it avoids it. (I
believe glibc's system() could reach it too with the right timing, but
I didn't try, my point being that the use of the OpenBSD system() here
is only because it's easier to grok and to wrangle.)
