The public\n// functions from those objects are not designed to be multithreaded. It\n// is not designed to support, for example, simultaneous Enqueues to the same\n// queue. This lock guarantees that the Queue can not have simultaneous Enqueues\n// and Flushes. There are a few CSurfaceQueue member variables that are shared\n// ONLY between Enqueue and Flush and do not need to be protected in CSurfaceQueue.\n// 2) A Semaphore to control waiting when the Queue is empty. The semaphore is\n// released on Enqueue/Flush and is waited on in Dequeue. \n// 3) A SlimReaderWriter lock protecting the CSurfaceQueue object. All of the\n// high frequency calls grab shared locks (Enqueue/Flush/Dequeue) to allow\n// parallel access to the queue. The low frequency state changes\n// (i.e. OpenProducer) will grab an exclusive lock.\n// 4) A critical section protecting the underlying circular queue.
