Description
How to cause images to be drawn in the midst of computations? (To show the evolving images as computations progress.) Where's a Matlab-style drawnow? The only way I've found to do this is inserting a sleep after imshow (or the sam after a push! into a Signal—not very “reactive” those signals). The sleep of course slows down computations and does not do anything in a Distributed thread (that would run on another CPU core and thus not significantly affect the computations) to have the drawing process in the background. It seems that the only way to force a redraw is to make Julia completely idle.

Research direction
Start by reproducing the issue with imshow and a Signal updated via push!, comparing the behavior with and without sleep. Read the image refresh path and the Distributed-thread behavior; done means computations can show evolving images without making Julia idle or relying on sleep.
