I was hoping to raise your awareness that you're up to something much bigger
than 'just' fibers. I didn't mean to offend and I apologize if I did.

I still don't get it. There is no API stability question. The API is well
defined for over 2 years now in the C++11 Standard (and even longer in
Boost.Thread). So performance is the main incentive for such a library (what
could there be else?). If you don't need the extra performance - use
std::thread.

Boost.Fiber does not add any new semantics beyond what the Standard
mandates. Instead, it adds more constraints to the context where the API can
be used (somebody mentioned interaction with Asio, and single-threaded
legacy applications) - thus it narrows down existing semantics.

Sure, that's out of question. My concern is that we're about to add a Boost
library targeting some minor use cases only, while it has the potential to
change the way we do parallel computing.
