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

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. http://bugs.python.org/issue6236
