The difference is exactly what you'd imagine - lm-send-async.c uses a
callback to get the response from the server (which means you don't have to
wait to see if the send was successful before your client can do anything
else) whilst lm-send-sync.c blocks whilst waiting for a response (i.e. you
have to wait for the server response before you can execute the next bit of
code).

er, good question. you'd have thought so but I can't find it instantly
(nothing I've done so far has needed explicitly it).
