* Implementation of query queue and host conditional rendering * Resolve some comments. * Use overloads instead of passing object. * Wake the consumer threads when incrementing syncpoints. Also, do a busy loop when awaiting the counter for a blocking flush, rather than potentially sleeping the thread. * Ensure there's a command between begin and end query.
