Re: [Matplotlib-users] ipython threading fails with macosx backend

[Brian G. <ell...@gm...>]

As I understand it the Mac backend uses the PyOS_ImputHook trick, which
means that no custom threading code is needed in IPython.  Thus it should
"just work" without any threading flags in both IPython *and* regular
python.  Just as an aside, wx is the only GUI toolkit that doesn't support
this "new" type of interactive usage.  We (ipython devs) are working with
the wx devs to change that.  Once that is done, we should be able to get rid
of all the nasty threading code in ipython.  More details will follow.

Cheers,

Brian
