/**
* Create a new queue with the given run loop and handler.
*
* @param runloop The run loop that will drive this queue.
* @param retainsObjects Whether the queue should retain its objects.
* @param handlerBlock An optional block to be run for each enqueued object.
*
* @discussion You may pass @c nil for the handler if you simply want the objects to
* be retained at enqueue time, and released during the run loop step. This is useful
* for creating a "main deallocation queue", as @c ASDeallocQueue creates its own
* worker thread with its own run loop.
