> If the Service Manager is killed-with-prejudice it can leave CUSTOM pingers alive and
orphaned (children of init).
> SM should clearly mark these processes so cleanup procedures can easily find them and
reap them as part of system startup.  The proposed mechanism is to set a -Dmarker as a no-op
system property to ServicePingMain that is easily discovered using ps.  Startup scripting
(and check_ducc) will look for these processes and kill them prior to starting SM.
> As well SM should implement a shutdown hook that attempts to stop these pingers if it
is stopped with only-a-little-prejudice.
