Hello,

I bet matz does not accept it because there is no good reason.
Why don't you extend the traditional Queue class?

The semantics is not trivial.  See the discussion in #4589.

Feature #6293: new queue / blocking queues

Hi,

I'd like to add new Queue objects to ruby.  Whenever I use queues, I either use them in a blocking or non-blocking manner only, so I have separated them in to two classes Thread::Queue, and Thread::BlockingQueue.

Other notable differences, these queues:

* implement `poll`, which will return a nil if the queue is empty
* do not allow `nil` to be in the queue as it would interfere with `poll`
* include Enumerable

I think these will be a good basis for implementing a Deque, SynchronizedQueue, and PriorityQueue.

I've attached a patch against trunk.
