The fact that biggest cpu manufacturer calls package "processor" today
means that term is clearly abgiguous, and better be avoided.

No, but new functions/literature/documentation should better be
unambiguous.

g_get_concurrent_threads() would be one such option -- you really want
the api to return 2 on pentium 4 HT. (And while pentium 4 HT may be
called multiprocessor machine due to SMT, it clearly is not have 2
processors... which just shows how bad the naming got.)
