I failed to make it clear that multi-threading in no way requires
multiple processors (as has already been mentioned elsewhere in this
thread:-)

AIUI, under Linux, creating a separate execution thread is almost as
costly as forking another process, so programs tend to do the latter
rather than the former.  In contrast under OS/2, spawning a thread is a
very cheap operation, so multi-threaded programs are more common.
