[Python-Dev] Inspect Patch for IronPython (and Jython?) Compatibility

[Guido van Rossum]

Let's definitely add this to the trunk (2.6). It sounds fine to me as
a bugfix too, since (from your description) it doesn't change the
behavior at all in CPython.

I won't have the time to submit this, but I'm sure there are others here who do.
