Interesting to see. I might suggest using [[NSThread currentThread] sleepForTimeInterval:] instead of sleep() since it is native to cocoa. Other than that, completely perfect.

@unixpickle: [[NSThread currentThread] sleepForTimeInterval:] is incorrect because sleepForTimeInterval: is a class method. You mean [NSThread sleepForTimeInterval:] instead.

Ah yes you got my on that one. Generally when I am using Xcode, code highlighting is a quick way of telling of something is declared, but obviously we don't have that here :-P
