Some languages (like Erlang and Haskell) don't use native thread. They use  
their own threading models (like green threads) which much more efficient  
in such tests. But green threads could block all application if some  
thread is doing some long time blocking operation (like blocking I/O).

And some implementation of tests in The Great Language Shootout have  
serious bugs so don't trust those results too much.
