Chez Scheme can do this. In particular, I am currently implementing a 
high-performance lightweight threading system based on a work stealing 
deque and atomic CAS operations. It's for an implementation of APL on top 
of Scheme, and it should do quite well for number crunching. If you are 
interested, I would love to have real world code to benchmark.
