I'm new here, so this is probably a silly idea; but...
I wonder if a page called something like [[wikipedia:Current edit wars]]
might be a good idea. When somebody spots that they or others are
becoming involved in an edit war, they could put a link on that
page.
That way, "outsiders" with less of a stake in that particular
war might be able to contribute some neutrality.
Just, y'know, a random passing thought.
