It's better to add the ability to recreate a socket if it encounters
trouble. SO_KEEPALIVE is there to help you detect if the other end of
your connection has disappeared.

Network programming has relatively few absolutes - it's best to build
in error checking and sometimes, error responses that go beyond mere
error messages.
