I ran through around 20,000 children on RHEL5 before I quit, and it didn't
crash using bash-4.2.28.  However, there is a change in the development
branch that does a better job of not running the SIGCHLD trap in a signal
handling context.  That's the only change I can see, though it should not
matter because the posix mode toggling means that code isn't executed.
