there's no problem if the server is single threaded and only serves
one request at a time.

the problem you speak of can only happen if two threads are both
trying to recv at the same time, but that can't happen if clients
always write before they read (and the channels are synchronous), as
all the clients will queue up to write to request, and the server lets
them through one at a time, sending the reply back before it lets the
next one in.

try modelling it in spin...
