I'm fairly certain that the signal issue you they are dealing with
is how to keep children from killing the init of a pid namespace.
At least that is what Suka mentioned when I asked him earlier,
and that is the discussion I have at various times on the containers
list.

This is a totally different issue.  This is keeping
kill -1 in a child pid namespace from sending a signal to
every process in the system.

It is a bad bug and this patch is a complete fix for it.
To my knowledge Pavel and Suka just overlooked this case.

I explicitly asked Suka, Pavel, and Cedric how complete they thought 
the pid namespace was before I started sending patches.  With
Pavel at a conference it makes sense why he did not reply.

For the most part Suka and Cedric did not know about the issues
that I have been finding and fixing.

So since several of them have been fixable with trivial simple fixes
and because we have passed -rc1 and it is now time for bug fixes
and possibly a few cleanups.  I have been making bug fixes.

Kir I am happy from feedback from people who can understand the code
and patches.  But I am not going to hold up sending simple obviously
correct fixes for discussion.
