Firstly my sincere apologies to Jim for bringing this up after such

Secondly: I think this approach is unnecessarily complex. I think
it's
sufficient to simply check whether the target process is in the right
process group before sending a signal, i.e. getpgid(pid) == getpgrp().
This ensures that the parent will only kill things it created.
If:
1. The required getpgid/getpgrp functions are available
on all current systems, and...
2. it provides as much protection as the more...
"exacting"... check, then
I have no real push one way or another...
