well... kind of.
THere are 2 things around pid namespaces: which pids you can see/touch
(in proc or signals or otherwise), and the non-uniqueness.
For containers you clearly want the first part... but... is there a
strong reason to not just *not* create duplicate pids even across
namespaces? there's no rule in posix or anything similar to fd's afaik
concerning which pids we can hand out... so we could just make then
unique globally but just with limited visibility....
