It's an interesting puzzle. I'm still pondering what the direct consequence would be if the
pid number would be completely de-coupled from the container logic (pid numbers are unique
within the system and don't try to magically encode container membership).
The only theoretical problem I currently see is that creating new processes will show you how
many new processes were created in the whole system (not just this container), but is that
really that bad? Or is it just a part of containers not being "invisible"? Because containers
simply aren't invisible and this one little piece of more evidence that they aren't isn't
really that big a deal.
But somebody will hopefull proof me wrong and point out that this really is a big deal ;-)
