You pointed only one problem that is not a variation of "how do 
we handle the case when we pass our pid outside the namespace".

This problem with signals is now being resolved at IBM by Sukadev 
and Serge (I put them in Cc), so this is about to be fixed by the
time 2.6.24 releases (I hope).

As far as the "passing the pid outside the namespace" is concerned, 
is my answer "pids should never be used outside the namespace they
came from, otherwise userspace won't work as expected" satisfactory?

So is "everything else", you mentioned, covered with the problems
above?
