Description Tim Horton 2013-04-17 19:39:41 PDT
For clients who are totally A-OK with the UIProcess blocking (for up to 250ms) until:

a) the TileCaches are reparented
b) the TiledCoreAnimationDrawingArea has reattached the layer tree to the layer hosting context
c) the runloop cycle has finished (so that painting can occur if necessary)

Actually I think it's bad that we could be coalescing here.
