I've had similar problems but not readily reproduceable.  I have an old
CM SPL process manager (~60 sons).  It doesn't wait for sons, but rather
uses local RINs to synchronize a common data segment for communication
(old pre-IPC application).  I've had it hang, or rather won't terminate
and keeps the sons alive.  It gets a timer bump every 5 minutes and then
queries the sons (getprocinfo).  I haven't reported it yet since it is
so bizarre -- could be shared data segments, local rins, process handling
code, or who knows.  It sits there for maybe 10 minutes, maybe a couple
of hours, but it eventually goes away.  The process cleanup is rather
CPU intensive once it gets around to dying.  Weird.
