Thanks for the feedback!  Much appreciated.

In theory, gui_thread could be extended to work for PyGtk also but
that will take time and effort and most of all a reasonably intimate
knowledge of PyGtk.

Well, I took a long while tracking this one down.  Considering that I
wrote an earlier version of this a long while ago, I can completely
understand the difficulty.  I think Pearu's approach is really quite
elegant and works well.  My primary difficulty was figuring out where
the problem was!

I have a question that you might be able to help with.  I want to do
this:

    Create a module that shadows an existing module in the filesystem.
    Lets say, site-packages/wx/__init__.py.  I want to create a new
    module with code that does something else (and not have to create
    a file!).  Like say: "def f(): print 'hello world'", call that the "wx"
    module, and make Python believe nothing is wrong (insert it into
    sys.modules or whatever) then do a 'reload(wx)' to re-read the
    real __init__.py just like normal.  I'd like the code to be simple
    and not have to use complex import hooks.

Is this possible?  If it is I could probably eliminate the wxPython
patch.

cheers,
