Best tip is to check the output of "os.popen('ps')" .. to some this will
seem like cheating, but trust me it isn't. <wink>
Another way could be to poke around in the /proc-directory...

If you already have a pid and want to check if the program is running, you
can try to send it signal 0 by doing a "os.kill(pid,0)". This will raise an
OSError if this isn't a running process.
