Unlock au-\u003elock\n\tbefore return.\n\t(init_adv_cond): Do not initialize lock.\n\t(enqueue_transfer): Unlock after signal.\n\t(enqueue_done_id): Likewise.\n\t(enqueue_done): Likewise.\n\t(enqueue_close): Likewise.\n\t(enqueue_data_transfer): Likewise.\n\t(async_wait_id): Do not lock/unlock around signalling au-\u003ework.\n\t(async_wait): Unlock after signal.\n\t* io/async.h (SIGNAL): Add comment about needed au-\u003elock.\n\tRemove locking/unlocking of advcond-\u003elock.\n\t(WAIT_SIGNAL_MUTEX): Add comment. Remove locking/unlocking of\n\tadvcond-\u003elock.  Unlock mutex only at the end.  Loop on\n\t__ghread_cond_wait returning zero.\n\t(REVOKE_SIGNAL): Add comment. Remove locking/unlocking of\n\tadvcond-\u003elock.\n\t(struct adv_cond): Remove mutex from struct.\n",
