Concurrent Haskell is designed to provide exactly the kind of
lightweight concurrency you're after.  It won't be as quick as a custom
application-specific threading model in the way you describe, but it's a
*lot* faster than using one OS-thread for each thread in your system.

And if you find it to be still too slow for your application, we know of
several ways to speed it up...
