Well, what happens if you do have the limit set at 1024, and a new
connection would bump it past that? Presumably accept() gives EMFILE,
innd logs the error, and the client sees an immediately closed
connection. So innd could just do the same (explicitly closing the
socket - perhaps even writing an error message to it first) if accept()
returned an fd that was >= FD_SETSIZE.
