Which brings up a purely theoretical question.

Wouldn't it be possible to write a system-dependent extension
that used native (kernel-level) threads?

Do POSIX threads (pthreads) have a kernel-level option? If so, then
they'd be fairly portable... Somebody told me a week or two ago
that there was such a thing as kernel-level pthreads, which surprised
me as I'd never heard that before...
