[Python-Dev] Rewrite os.popen using subprocess.Popen?

[Nestor]

pydoc.py uses os.popen once on line 1359. According to the
documentation that function is deprecated since Python 2.6. Does it
make sense to rewrite that line using the newer subprocess instead?

I am asking because os.popen stopped working for me in Python 3.1 but
I don't know if it is worth investing time in a module that is
deprecated when the newer one does work.
