commit 81b18e513c41e0e025fc785a16df2c1a63e9551c

    Fix another process stuck-during-exit bug - stuck due to signal.
    Fix a bug where an exiting process becomes a zombie, entering the SZOMB
    state, but then receives a stop signal before it can be reaped.  If this
    occurs the process was incorrectly placed in SSTOP and then later made
    SACTIVE again, preventing it from being reaped.
    Symptoms were: process shows up in ps in a DEL state but does not show
    up in kgdb's 'info thread' list.  Process is the zombie list and is still
    a child of init, but it's state is SACTIVE instead of SZOMB and p_xstat
    (last signal taken) is SIGSTOP or SIGTSTP.
