Well, the file requested doesn't have anything to do with what
PythonHandler specifies, e.g. in your example it will respond just the
same with requested url of "/mptest/blahblah.py/abc/123" instead of
"/mptest/mptest.py/abc/123". The question then becomes should SCRIPT_NAME
be "/mptest/mptest.py" or "/mptest/blahblah.py"?

It sort of does. There is a place in requestobject.c where it removes the
trailing slash for something, then puts it back, and now I don't remember
why it does it, but it was some rather esoteric condition that caused
apache to infinite-recursively call some function... Since I don't
remember what the reason was, I was always hesitant to remove that bit of
code. It was put in years ago back in the apache 1.2 days, so it might be
safe to remove in 2.0... I guess we can try it at least.
