Package queue includes a regular queue and a priority queue.
These queues rely on waitgroups to pause listening threads
on empty queues until a message is received. If any thread
calls Dispose on the queue, any listeners are immediately returned
with an error. Any subsequent put to the queue will return an error
as opposed to panicking as with channels. Queues will grow with unbounded
behavior as opposed to channels which can be buffered but will pause
while a thread attempts to put to a full channel.
Recently added is a lockless ring buffer using the same basic C design as
found here:
http://www.1024cores.net/home/lock-free-algorithms/queues/bounded-mpmc-queue
Modified for use with Go with the addition of some dispose semantics providing
the capability to release blocked threads. This works for both puts
and gets, either will return an error if they are blocked and the buffer
is disposed. This could serve as a signal to kill a goroutine. All threadsafety
is acheived using CAS operations, making this buffer pretty quick.
