Have you implemented this in a way that is interchangeable with 
swapcontext ?  For example, could I take your optimised implementations 
and use them with e.g. Boost.Coroutine ?  If this part of your work 
could be factored out and used independently, rather than being left as 
an implementation detail, that would potentially increase the 
usefulness of the contribution.

Also, do you have any observations on why swapcontext is slow?  On what 
platforms have you measured this?

If you need any help with ARM I may be able to assist.
