[Tutor] threads

If what you want is something that scales up, then you're attacking
the Wrong Problem.  Rather than focus on getting your thread overhead

as you can, you should (as has been suggested) try to get
simulation-time concurrency without worrying about what happens in
real-time. Then you can have arbitrarily many things happening at
once.
