The ruby interpreter isn't multithreaded, so it won't take advantage of
SMP sytems.

The interpreter doesn't support multithreading itself, so all
ruby-scripts will only use 1 Core, even when they create ruby-threads.
But maybe you can use more than 1 process (e.g. call "fork" instead
creating a thread). Your OS will (hopefully) schedule the second
interpreter on the second core.

Actually, most second cores on desktop machines (and Windows servers)
are already too busy processing all your spam and viruses. ;-)

You have to do something special.
