If one looks at the documentation/tutorials for matplotlib (-pylab), Mayavi (-
wthread), ... one finds that for ipython you need to start it with an extra 
parameter (the ones mentioned in parens above). The problem being that for GUI 
tools in order to function within the same process there's an event loop. But 
an interactive shell is somewhat of an event loop in itself. So some de-
coupling needs to be done to integrate the two event loop concepts with each 
other. ipython provides that through the switches.

I'd imagine that this was also one of the motivations to provide VIDLE over 
plain IDLE, although I've never used IDLE myself. Maybe one of the provided 
ipython switches would also help with VPython, or another one would need to be 
created to make them interact nicely. Definitely sounds like something that 
could be quite useful ...
