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.
