There seem to be two ways: either you make the read blocking
(which will prevent you from doing anything until a reply
arrives), or use a separate thread to read (again blocking).

For apps handling async events using threads is really the
'natural' thing to do. If multithreading is new to you, now
is the time to jump into it !
