I can't tell from the sparse information, but if you were using the
System V environment it is possible you were getting an emulation of
the System V SIGCLD behavior.  I know it was present in my original
System V emulation for 4BSD, even though I personally think it is a
horrible design and that the originator of that kludge in UNIX System
V should be hanged by its thumbs.
