This is why I suggested a cooperative thread system at one
point. Callbacks that would add 10,000 elements to a tree view could
simply call yield() in between each item. Then the main loop could
prevent it from running again if it wanted to start painting.

There are some potentially nasty reentrancy issues though, and of
course it would require a bit of assembly for each platform it would
run on.
