There are probably smaller details floating around, but that's the
most important one.

WRT multiprocessing and GUIs, we have a wxPython application that
starts up a Process (that does not use a GUI) just fine on UNIX and
Windows.

But why the sudden interest? And why on this list rather than
ipython-devel where we've discussed these issues before?
