Continuations for Mono

Tomi Valkeinen has implemented continuations for the Mono virtual machine.

His continuations work is here.

Most of his tests are used for a user-level thread implementation he calls Microthreads.

This looks like a very nice addition, and Paolo seems to like it too. In the past I abused C# iterators to get some of the benefits of continuations in Mono's ASP.NET (the HTTP processing pipeline).
