By the way, note that in the latest ASIO (boost 1.37.0) the
synchronous operations are thread safe:

Updated Libraries
Asio:
* Synchronous read, write, accept and connect operations are now
thread safe (meaning that it is now permitted to perform concurrent
synchronous operations on an individual socket, if supported by the
OS).
