I tested patch 1/2 and 2/2 on next-20150929 using reproducer at
http://lkml.kernel.org/r/201503150240.GII00591.OVSFtQLOFOHJMF@I-love.SAKURA.ne.jp .

  $ while :; do ./a.out; done

Unfortunately, since hangup on coredump to pipe occurs sometimes,
I can't tell whether this patchset solves hangup on coredump to pipe.
