Which API are you using?

With the raw API you will either get your error callback or your receive
callback called with length of 0 when the connection is closed.

With the sockets API a call to recv() will return 0.

(I think - this is from memory, rather than checking the source).

Presumably in your server you have to restart the accept when the
connection is closed "naturally". i.e. when the client is done.  How do
you deal with this?  Can't you just do the same when the connection is
closed due to a keepalive failure?
