Python/wxPython Reducing memory usage.

[lotmr]

I have previously posted a simple app I am working on, and while I love
python and wxWindows, after checking the memory usage on such a simple
app (system try application launcher) I see that it climbs to over
17mb! I have reduced all my imports to the bare workable minimum and
that just gets it under 17mb. Is there any way that I could compile or
optimize the my program and/or its memory usage?
(Note: I don't have a problem with making this program win32 specific,
as it already is only win32)

.... and ideally, if we could also reduce the size of the DLL, so that
it would only include the widgets actually used, it'd be even nicer.

I don't have much experience with it, but is the PythonWin wrapper to
MFC horrible to use as compared to wxWidgets? If it's good enough and
you don't care about non-Windows platforms, you'll probably save a lot
of RAM and file footprint.
