I personally like Edward Loper's idea of just running your own event
handler which deals with drawing, suspend/resume, etc...

...but even without posting and reading events as stated above, one
could check for plot events every 1/100th a second.  If there is an
update, and it has been 10/100 seconds since that undrawn event happened,
redraw. Tune that 10 up/down to alter responsiveness characteristics.

Or heck, if you are really lazy, people can use a plot() calls, but
until an update_plot() is called, the plot isn't updated.

There are many reasonable solutions to your problem, not all of which
involve changing Python's event loop.
