Lock free multi producer multi consumer queue ring buffer

Nowadays, high-performance server software (for example, the HTTP accelerator) in most cases runs on multicore machines. Modern hardware could provide 32, 64 or more CPU cores. In such highly concurrent environments, lock contention sometimes hurts overall system performance more than data copying, context switches and so on. Thus, moving the hottest data structures from a locked to a lock-free design can improve software performance in multicore environments significantly.
