You'd have to do the same thing that users of the other script languages 
do, they only perform limited computation and if their computation is 
incomplete, they yield and pick up later. The real issue becomes a 
matter of how light weight are ruby threads/objects and exactly how many 
do you expect to be running at once.

Also, the JRuby and IronRuby stuff looks promising at increasing the 
speed of ruby drastically.
