I haven't tested your patch, but I'm asking myself whether it cooperates
with autorevert triggered by file notifications. That is, if a file
changes on disk, a notification event is sent, and autovert happens. If
autorevert does not happen because the buffer is not visible, this event
will be lost, and no autorevert will happen later on when the buffer
becomes visible.

Have you tested this scenario?

Best regards, Michael.
