If you really want to be 100% correct about it you can change the
interface to read_socket_with_timeout() to modify the timeout value
to eat up the elapsed time before it returns. That way multiple calls
with the same &timeout variable will only sum to the total timeout.

And also it means we don't pay the time processing penalty on server
code (which is what I really care about :-).
