Abstract
A first thread is placed into a blocked state by causing the thread to perform a blocking pop operation on a hardware-accelerated, single-entry queue. When a synchronization event completes, a second thread may release the first thread from the blocked state pushing a data value onto the hardware accelerated, single-entry queue. The push operation satisfies the blocking pop operation, and the first thread is released.
