And thanks to @mikeash a third time for pointing out that -pop was crashing instead of returning nil on an empty queue. And for suggesting -respondsToSelector: to check for secure coding support so builds against 10.7/iOS 5 will use it on 10.8/iOS 6.

Thanks to @mikeash (again!) for pointing out that pathological array contents could deadlock if the encode is done on the queue's queue.

DRAtomicQueue

A thread-safe FIFO queue for Objective-C. I had intended to build it on OSFIFOQueue, but that doesn't exist for iOS. Then I was gonna implement my own, but lockless queues aren't really possible without a true DCAS instruction, which also doesn't exist. As a result, this is just a somewhat lame wrapper around NSMutableArray and libdispatch. It is cool and supports everything, though.
