Actually many thanks for this very interesting discussion!  Just on
Friday I came to this same conclusion while preparing some lecture
material using animations.  The lack of a clean pause/restart
functionality is indeed problematic.  Furthermore, closing a window
that's running an animation, at least with the Qt backend, gave rise
to a massive swarm of 'C++ object has been deleted' messages flooding
the console where my ipython kernel had been started.

One thing to keep in mind, if you go down the road of implementing a
full-blown event loop for matplotlib, is how well it will play with
existing event loops. Whenever an interactive GUI backend is running,
there's already an event loop at work: that of the GUI toolkit.
Integrating multiple event loops in the same process takes some
delicate footwork if you don't want to end up with a nasty fight
between the two.

In any case, keep us posted on any progress!

Best,
