The function cm_work_handler() cannot touch the cm_id after it derefs it, because it might be freed on another concurrent thread. If there are more work items queued for this cm_id, then we know there must be more references because they are added when the work items are queued. So in the while loop inside cm_work_handler(), after derefing, if the queue is empty, then exit the function. Otherwise we know it's safe to re-acquire the lock.
