> You are correct. They are two different things:

Alright, does the following assertion fail when placed before the
-performSelectorOnMainThread line? (Ignore the warning - using private
APIs.)

    id a = (id)[[[NSThread mainThread] runLoop] getCFRunLoop];
    id b = (id)CFRunLoopGetMain();
    NSLog(@"%p ?== %p", a, b);
    assert(a == b);

    [anObject performSelectorOnMainThread: ...]

Please respond with the output of the NSLog line too.

The assertion succeeds in my own test app. I'm guessing it
fails/crashes in yours.
