Opening a file shouldn't do anything if the file is already open, even if
the file has been updated. That's just normal opening procedure of
documents. So I do think this behavior is basically correct. Also because
the script doesn't know about updates. However the file update checking
should reload the file in this case, and that's what I'm talking about. So I
think we should run a timer when  the file is deleted to see if the file
comes back, because kqueue is useless in that case.
