I think the fix is in version 1.113 of lib/libpthread/pthread.c.

        * pthread.c (1.113): Don't just look only at the first element in
          the deadqueue to find lwp's to reuse, because if we lose the race
          with the kernel we are never going to reuse any elements. Look in
          the whole list instead.  XXX: should be pulled up to 5.x
