[M3devel] pthreads problem, LINUXLIBC6, RHEL 5.8

Return code in question is 22, EINVAL, code is

      WITH r = pthread_cond_timedwait(self.cond, self.mutex, until) DO
        IF r = Uerror.ETIMEDOUT THEN
          WITH r = pthread_mutex_unlock(self.mutex) DO <*ASSERT r=0*> END;
          IF perfOn THEN PerfRunning() END;
          RETURN;
        END;
        IF r # 0 THEN
          RTIO.PutText("r="); RTIO.PutInt(r); RTIO.PutText("\n");
          RTIO.Flush();
        END;
        <*ASSERT r=0*> --- former line 586

...
       The pthread_cond_timedwait() and pthread_cond_wait() functions may fail if:

       EINVAL The value specified by cond, mutex, or abstime is invalid.

       EINVAL Different  mutexes  were supplied for concurrent pthread_cond_timedwait() or pthread_cond_wait() operations on the
              same condition variable.
