Bash Version: 3.0
Patch Level: 16
Release Status: release

Description:
        Bug at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=224543
        (reported back on 2.05) still exists on 3.0... re-reporting
        to bug-bash so hopefully it gets noticed.

        Bash is apparently improperly setting up process groups in
        a way that causes processes to become stuck in the STOPPED
        state.

Repeat-By:
        env -i EDITOR=emacs TERM=linux SHELLOPTS=monitor bash --noprofile 
--norc -c "while true; do crontab -e ; done"

        Hit ^X ^C rapidly to keep exiting emacs.  Soon, a copy hangs on
        startup, process in stopped state (T), cannot be restarted with
        SIGCONT, only killed with SIGKILL.

Fix:
