I use the Cygwin ps.exe program.

I can run it from the commandline inside of my pl's and do damage from there. Cygwin utilities are very portable for win2k and above. I copied the cygwin1.dll and ps.exe into my own perl directory and i am completely portable (optional of course). Perl can kill your pid's with a simple kill statement.

P.S. cygwin has loads of cool stuff in it. worth exploring in detail.
