Just a remarks related to name space. Your namespace approach is mixed. From
one side you have boost::this_fiber namespace and boost::fiber class and the
namespace boost::fibers. IMO you should either put all on boost or on
boost::fibers but not both.

Instead of 

boost::fiber f1=boost::fibers::make_fiber( some_fn);

I would prefer 
boost::fiber f1=boost::make_fiber( some_fn);

I have also some questions related to the scheduler. How many schedulers can
be run on a thread? Do you have a use case of any interest to be able to run
more than one?

Could you talk about the need to migrate fibers from one thread to another?

Thanks,
Vicente
