[Python-Dev] Review popen fd leak fix

[Neal Norwitz]

There are fd leaks in popen2 when exceptions occur.  It would be nice
to get the fix into 2.3.  Could others review the patch attached to
the bug:

        http://python.org/sf/761888

There may also be some relation to bug 768649, but I'm not sure since
I can't reproduce the problem.

Thanks,
Neal
