Allo monks, I have a strange, strange puzzle for you. I have a class library built that uses a symbolic reference for SIGTERM. Basically, its 
$SIG{TERM} = "sigterm_handler";

[download]
I do this basically so each app that uses this class can have its own set sigterm handler.

Now, this is where the wierdness starts. First, I start up multiple instances of the same perl script which is using this class. They have different PIDS and PGIDs but the same PPIDs and SIDs.

Now I send a SIGTERM (basically "kill <pid>") to ANY of these processes.. and the rest also receives the SIGTERM! I'm fairly sure its a clean SIGTERM exit because I log in the handler. But now if I remove the sym ref in the class, this DOESN'T happen.

This is just so odd to me. How would sending a SIGTERM to one process propagate to another? I need help.. and an Advil.

TIA
Mike
