 Sky's Run Loop
 ==============
 
 Sky's run loop consists of running the following, at 120Hz (each loop
 takes 8.333ms):
 
 1. Send scroll and resize events if necessary, limiting each handler
    to 1ms, and limiting the total time spent on these handlers to 1ms.
 
 2. Fire animation frame callbacks for up to 1ms. Each callback can run
@@ skipping 13 matching lines @@
 
 5. Update as much of paint as possible; after 1ms, throw a (catchable)
    EDeadlineExceeded exception, leaving any remaining nodes
    unprepared.
 
 6. Send frame to GPU.
 
 7. Run pending tasks until the 8.333ms expires. Each task may only run
    for at most 1ms, after 1ms they get a (catchable) EDeadlineExceeded
    exception. While there are no pending tasks, sleep.
