Actually, there are more problems with system(3).  If you run make and hit
DEL, make kills the current compilation and starts the next one.  Klamer
Schutte posted a discussion of this a while back.  The problem appeared
when system(3) got signal handling, but apprarently the signal handling
merely exposed an underlying bug.  If anyone has time to figure this out,
please do so and post the fix.  It is kind of annoying not being able to
kill make.
