Just so I understand, do you mean for the pthread_* APIs like pthread_mutex_timedlock, pthread_cond_wait_timedwait etc that are time based, to have more specific delay behavior (currently, the new flags support customizing delay behavior for 1) relaxed atomics, 2) stronger than relaxed atomics, 3) all mutex/cv ops). Or something else?
