fix and optimize non-default-type mutex behavior problem 1: mutex type from the attribute was being ignored by pthread_mutex_init, so recursive/errorchecking mutexes were never being used at all. problem 2: ownership of recursive mutexes was not being enforced at unlock time. 2011-03-08 03:41:05 -05:00			`if (a) m->_m_type = *a & 3;`
