title: Use Python 2.6 subprocess module in Python 2.5
body: <p>I would like to use Python 2.6's version of subprocess, because it allows the <a href="http://docs.python.org/library/subprocess.html#subprocess.Popen.terminate" rel="nofollow noreferrer">Popen.terminate()</a> function, but I'm stuck with Python 2.5. Is there some reasonably clean way to use the newer version of the module in my 2.5 code? Some sort of <code>from __future__ import subprocess_module</code>?</p>
