Erik Nygren noticed some stray jhawk (uid 10786) processes on steve-dallas
(IRIX 5.3, Athena 8.0K).
One of them, pid 28875, is a defunct/zombie process that is parented by init.
My understanding is that it is init's responsibilty to reap
zombie children which it inherits.
This does not appear to have happened here, and I don't know why.
Either my understanding is flawed or this is an OS bug.
Note that 28875 does have children (one zombie and one not), but
I don't think this is pertinent.
Attached is ps -elf output.
