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
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
