Is
    5) Free

also a requirement?  If not, there should be a few options - LispWorks
on the Common Lisp side and FunDev on the Dylan side both have
threads.  You might
check out ECLS, which is free and was threaded at least at one point
in its development (not sure about the current codebase).

You should also take a look at SmallScript, which is not yet available
for unix but can be previewed for Win32; it's ST-80 + a whole whack of
stuff (including multimethods) and minus the way of life.
