Subject: launching process and keeping track of pid

Hi,

How can I launch a program from Ruby and monitor it to see if it's
running?  On a unix platform.

I assume I'd probably need to launch the program, capture the pid of
the started process somehow, and start a thread that monitors the
/proc directory to see if the pid is in there?

Thanks,
Joe
