No, you send CONT to all processes (like 'pkill -CONT .'), it seems that
this gets whatever was wedged enough of a kick to retry or time out and
then it (often, not always) it seems to start reaping processes again
and the <defuncts> start to vanish.  You can tell you have one of these
when just doing a ps takes much longer than usual when it hits those
processes.
