I'm not suggesting it's a bug in bash.  If anything it's a bug
in the script.  You should never do a naked wait unless you are
sure that there are no other children around that you don't know of.

In the original bug, the proper solution is to wait on the PID
that the script just sent a kill signal to.

Cheers,
