Nice. I quickly looked at the code, looks like you (or Paolo?) quite much 
rewrote the whole thing =).

Does the new implementation suffer from the same crasher problems as the 
previous one, like managed-native-managed transitions in stored stack, or 
restoring continuation above the mark?

I don't know... I haven't touched the continuation stuff for a couple of 
years now, and I've been very busy with linux kernel development. I 
believe "hosting" here means some kind of maintenance burden, so I think 
I'll have to say no thank you.

However, I grant everyone rights to do anything they want with my 
microthreading code, so please host them on Mono's repository if you think 
it'll help people.

And I'm still of the opinnion that this stack-copying is more of an 
interesting hack, than something people should really use =).
