Another question about this 'CopyBits' inside VBL tasks.

Is there a potential problem if the CopyBits decides to move memory
around for you because it needs the space to draw a particularly difficult
bitmap?  Or is this one of those places the Quickdraw cheats and uses
memory between heap and stack that it thinks is fair game?
