Alias of #pop

Retrieves data from the queue.

If the queue is empty, the calling thread is suspended until data is pushed onto the queue. If non_block is true, the thread isn’t suspended, and ThreadError is raised.

If timeout seconds have passed and no data is available nil is returned. If timeout is 0 it returns immediately.
