Bug#549376: Possible related upstream bug

["Chanoch (Ken) Bloom" <kbloom@gmail.com>]

Could https://bugzilla.mindrot.org/show_bug.cgi?id=271 be related?
I notice in my strace that OpenSSH blocks SIGCHLD repeatedly, but
when rt_sigprocmask returns the old mask, it doesn't include SIGCHLD
in it.

https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/412972 also
looks related. I'm noticing the same SigBlk: fffffffe7ffadeff in
/proc/1930/status where 1930 is the pid of the root sshd (the parent
of all of the others).
