Jake's observation is certainly true but it's not really doc-view
specific.  A similar case is shown by this recipe:

1. open dired for /tmp and enable dired-omit-mode and auto-revert-mode
2. visit a different buffer
3. touch /tmp/foo in a terminal
4. observe the message "Omitting XX lines in /tmp"

So Jake's request can be broadened to something like "buffer-bound modes
should suppress messages when their buffer is not visible".  I'm not
sure if I'd want that.  And how to implement it.  I guess we certainly
don't want to visit each (message...) in Emacs to check if it's
appropriate to show in the "buffer not visible" case...

Bye,
Tassilo
