That function assumes the io_service associated with your socket is
*stopped*, so it cannot run either in one thread or in multiple threads.
Note that it is an async. implementation for *synchronous* use, and when you
use sync. i/o you do not explicitly run io_service:

io_service io;
tcp::socket sock(io);
// open socket, define your buffer..., then:
read_with_timeout(sock, buffer);

But if you've already got an async. design, you don't need workarounds to
implement timeouts - just use deadline_timer in the straightforward way.
