One popular technique for network I/O is to watch the network socket
for incoming data, then call read() when you know there is something
to be read.  The poll() and select() functions are the traditional
ways of doing this.  libevent and libev are probably more convenient,
if you want to support multiple-platforms.  Or if you're developing a
glib application you can use GIOChannels.
