unify and overhaul timed futex waits new features: - FUTEX_WAIT_BITSET op will be used for timed waits if available. this saves a call to clock_gettime. - error checking for the timespec struct is now inside __timedwait so it doesn't need to be duplicated everywhere. cond_timedwait still needs to duplicate it to avoid unlocking the mutex, though. - pushing and popping the cancellation handler is delegated to __timedwait, and cancellable/non-cancellable waits are unified. 2011-08-02 21:11:36 -04:00			`static void dummy(void *p)`

fix pthread_join wait call: thread termination tid futex is not private this seeme to be the bug that prevented enabling of private futex support. i'm going to hold off on switching to private futexes until after the next release, and until i get a chance to audit all wait/wake calls to make sure they're using the correct private argument, but with this change it should be safe to enable private futex support. 2011-09-09 23:10:27 -04:00			`if (tmp) __timedwait(&t->tid, tmp, 0, 0, dummy, 0, 0);`
