A closed socket is marked ready for reading. read() then returns `0' to
indicate the socket was closed.

Don't let yourself be fooled by the "exception" fd_set; that's for catching
OOB data (MSG_OOB). Something you'll probably never need.

Also, you want to make sure all your sockets are non-blocking and check
for read/write returning -1 and errno set to EWOULDBLOCK. That can be
kind of tricky (but it feels really great once you get it to work).
