you can use the mutexes from bosot.fiber in a multi-threaded env
(but you have to use fibers in your code).

yes - unit-test test_migration shows how it is done

fibers run concurrently in one thread - if you want to use more CPUs you
have multiple choices:

1.) you assign one io_service for each CPU (fiber migration could be done
via a specific fiber-scheduler)
2.) you have one io_service and each CPU executes io_service::run() - you
have to execute the fibers in one strand
for each CPU (not tested yet)
