Hmm, I did not know that --gthread also worked, I thought only
-gthread and -wthread worked.  The gthread option is really not doing
anything fancy at all.  All I've added is a function that updates
Tkinter when the timer is called and removed gtk's own mainloop with a
hijacked version.

wxPython-2.4 is I think is more reliable and should work out fine.
You'll need my updated patch that I just posted though (it just
changes one line).  

To improve the hijacking can you just check these out and let me know?
Does wx._core have a _core_ attribute?  If so, then you really need to
access wx._core._core_ and hijack that, this works for me also, so if
this works for you, I'll make that the default and we won't need any
of the hasattr checks.

Does this hijacked hijack_wx work fine or does it still freeze?

Thanks!
