If you're on Linux you should

* Have a look at the /proc/ filesystem, there's probably what you want
there.

Here's a small script that print all the pid/cmd from the process ran
with your user.

#!/usr/local/bin/python

import os
import re
import stat
from os.path import join

for pid in (pid for pid in os.listdir('/proc') if re.match('\d',
pid)):
    cmdline_fn = join('/proc', pid, 'cmdline')
    cmdline = open(cmdline_fn).read()
    uid = os.stat(cmdline_fn)[stat.ST_UID]

    if os.getuid() == uid:
        print pid, cmdline


For a more cross-platform solution there's a module that does that (I
forgot it's name but with some googling you might find it)
