Lang Hames 2ca233e645 [Orc] Re-enable the RPC unit test disabled in r286917.
This unit test infinite-looped on s390x due to a thread_yield being optimized
out. I've updated the QueueChannel class (where thread_yield was called) to use
a condition variable instead. This should cause the unit test to behave
correctly.
