Is there a way to get the process id when starting a process using
os.popen2 or os.popen3 on linux?

on Unix, os.popen2/popen3 uses functions and classes from the popen2
module. they return file objects attached to the process, but there's
no (non-hacky) way to get at the process itself.

if you need more control over the subprocess, you can use the classes in
the popen2 module, or, better, the subprocess module.
