#1 Add a lockless queue.

[Tyler Durden]

Request for a lockless queue implementation ala: http://ldk.sourceforge.net/LocklessQueue_8h-source.html.

Need to investigate how the above queue actually functions, as at first glance this does not seem to guarantee atomicity.

Followups: Should the AsyncQueue simply be a lockless queue? It looks like this is not the case since the lockless queue restricts the total amount of queued items.
