Yes, I am aware of this.  I was generalizing.  However, SIGCLD/SIGCHLD
behaves in this context as if it were an interrupt in that it will be
reissued immediately if not cleared before being re-enabled.

>Worse, SIGCHLD/SIGCLD is not even a UNIX signal, it's an abomination.

Agreed, albeit a useful one.
