In peer_send_msg(), we take a lock before calling peer_send_teach_process_msgs because of the check on the flags and update indexes, and the function then drops it then takes it again just to resume in the same situation, so that on return we can drop it again! Not only this is absurd because it doubles the costs of taking the lock, it's also totally inefficient because it takes a write lock while the only usage that is done with it is to read the indexes! Let's drop the lock from peer_send_teach_process_msgs() and move it explicitly in its only caller around the condition, and turn it into a read lock only.
