It is not a rare occurrence on mobile devices. On my tablet WebGL app's
lose their context every time the tablet goes to sleep. Since the
timeout is so short, it only take a brief distraction and "poof!" the
tablet is asleep. The loss can happen while the application is in the
middle of drawing the canvas.

P.S. Why do so many threads on whatwg get forked? My threaded message
viewer is now showing 3 threads with the title "Hardware accelerated
canvas".
