The fact that sockets are not thread safe and the usage of strand is
something no related each other.
The fact that ip::tcp::socket are not thread safe imply that you can
not use the same instance from multiple threads (two concurrent
async operation calls for example).
Some time you can not have concurrent handlers calls, so if you have
a pool of threads calling the io_service::run() you have to use
io_service::strand to serialize handler execution.
