wxpython, linux, multithreading (Xlib: unexpected async reply (sequence 0x187)!)

[Ville Vainio]

I tried to run a program that runs ok on win32 on rh73, wxgtk and
wxpython 2.3.2, the latest PythonCard, and got the following error:

Xlib: unexpected async reply (sequence 0x187)!

Apparently, this is because xlib doesn't like getting calls from many
threads at once. Is this to be expected? Is there anything that gets
"periodically" executed in wxpython mainloop, like there is in
tkinter, so that I could avoid manipulating the gui directly from
another thread?
