Thanks, already trying them.
What will happen on fiber::mutex.lock() call if all the fibers on current
thread are suspended? Will the mutex call `this_thread::yield()`?

Another implementation question:
Why there are so many atomics in fiber_base? Looks like fiber is usually
used in a single thread, and in situations when fiber is moved from one
thread to another memory barrier would be sufficient.
