Very few Unix systems *don't* have threads available these days. The
difference is that threads have been implemented as libraries, rather
than as kernel-level entities. Sun OS4 has liblwp (light-weight
processes) as a standard feature; Brown Threads and others exist as
publicly available implementations... Of course not all library-based
implementations are preemptive, but many are.
Of course, for Unix you can get specialised toolkits (e.g. ISIS), which
you certainly can't for OS/2.
