Yeah, that's true.  At least I can't come up with a good reason of
wanting to know which thread exactly you're running on.  Having said
that, from a user-perspective, looking at two entries in /proc/cpuinfo
and seeing that the socket id/core id are the same and only the thread
ids are different probably would give me more of a warm and fuzzy
feeling.

Yeah, I guess "MAX(thread_id) + 1" does count as a "calculation".  And
I thought computers where good at that... ;-)
