That's fine. I can be convinced away from "sibling", I'll leave that up
to others. Personally I think I prefer "virtual core" over "sibling"
and "sub-core".

However, "thread" is the least clear of the proposed choices, and should
not be used. Anything-but-thread is my position :) Thread is used to
describe processes in Linux, those active in hardware and also those
sleeping in memory, etc.
