Lets assume you want to send data from the main thread, while your
io_service is running in another thread. You can't access the socket
object in a straightforward way from the main thread without potential
race-condition, because it's being processed by io_service in another
thread. What you can do instead is to bind the data to a functor and
post it to io_service's thread (look at the io_service::post() method
for details) - this way you don't need to explicitly lock anything.
