Hi Vincent,
Sorry, I guess I'm being dense or something. Can you explain how a wait
can be "too late"? I understood that if a wait occurs after the child
has exited, the wait will reap the zombie.
Oh, wait, I just realized I may have misunderstood the issue. Are you
saying that the zombie exists while less is running but it does get
reaped correctly when less exits?
