Subject: [PATCH] Comparing dispatch_get_current_queue() with
 dispatch_get_main_queue() is not only deprecated since iOS6, but unreliable
 according to queue.h

When dispatch_get_current_queue() is called on the main thread, it may or may not return the same value as dispatch_get_main_queue(). Comparing the two is not a valid way to test whether code is executing on the main thread.
