        The file descriptor underlying a FileDescriptor may be closed and
        replaced by another at some point.  Bytes which arrive on the new
        descriptor must not be delivered to the FileDescriptor which was
        originally registered with the original descriptor of the same number.

        Practically speaking, this is difficult or impossible to detect.  The
        implementation relies on C{fileno} raising an exception if the original
        descriptor has gone away.  If C{fileno} continues to return the original
        file descriptor value, the reactor may deliver events from that
        descriptor.  This is a best effort attempt to ease certain debugging
        situations.  Applications should not rely on it intentionally.

            This L{FileDescriptor} will have its socket closed out from under it
            and another socket will take its place.  It will raise a
            socket.error from C{fileno} after this happens (because socket
            objects remember whether they have been closed), so as long as the
            reactor calls the C{fileno} method the problem will be detected.

    method is called.
