I seriously doubt it. It's all exactly the same as the _current_ 
/proc/<pid> stuff, it just shows up in a different place.

I worry about the _sanity_ of it, and it basically makes no sense to
iterate over every single thread, when you should always be able to just
iterate over processes (and then within the process - only when you want
to - iterate over the threads of _that_ process).
