[Bug nptl/4512] New: robust mutex does not work if owner died with multiple waiters

["anemo at mba dot ocn dot ne dot jp" <sourceware-bugzilla at sourceware dot org>]

If an owner of a robust mutex died with multiple waiters,
one waiter is waken with EOWNERDEAD.  Other waiters keep waiting
the mutex but never waken even if the new ownder unlocked the mutex (or died).

This happend only with non-PI mutex of glibc 2.5.
PI mutex works fine.
