You'll recall the ECHILD exception was installed by Tatsuo after seeing
problems on Solaris.  Evidently Solaris uses the auto-reap behavior too.

I'm somewhat surprised that HPUX does not --- it tends to follow its
SysV heritage when there's a conflict between that and BSD practice.
Guess they went BSD on this one.
