drawrect

I know that drawLayer: and drawlayer:inContext: are called on multiple threads when using a CATiledlayer, but what about drawRect:?

Apple's PhotoScroller example code uses drawRect: to get its images from disk, and it has no special code for handling threads.

I am trying to determine whether my model for a CATiledLayer must be thread-safe.
