Odd.  I just noticed that my system is pegged at 100% CPU, attributed to
a syslogd process; wonder if severe load is the culprit that violates
the timing assumptions in that test.  I killed that process, reran the
test, and no longer see the failure.

I'm wondering if I should tweak the gnulib test to use fork() instead of
system(), and maybe do a bit more handshaking, to guarantee that the
signal is being delivered when planned?
