This is my mistake done by ce7eb0e90315eb1939ac29f656d39b3db858c092,
I refactored lll_wait_tid and wrongly assumed __lll_timedwait_tid is
a cancellation point. The lll_wait_tid is only used on
__pthread_timedjoin_ex and replicated on arch lowlevellock.h
implementation, I think it would be simpler to just move it to
nptl/pthread_join_common.c.
