boost.context isn't related to threads.
It doesn't deal with context switches related to threads (the kernel
doesn't see switches done by boost.context).
from docu: 'A context switch between threads requires system calls
(involving the OS kernel), ... By contrast, transferring control among
boost.context requires only a few hundred CPU cycles because it does not
involve system calls as it is done within a single thread.'
