recorded when the edit UI is first opened, not when the delete button is
hit.

the second one to get a message that it no longer exists. Or just to
silently fail to delete the deleted page..

* Alice deletes a page; Bob had edit window open for it, and saves
it afterwards. I think that Bob should win in this case; Alice can always
notice the page has been added back, and delete it again.
+ Update: Bob wins.
* Alice clicks "rename" button for a page; Bob makes a modification;
Alice confirms rename. This case seems easy, it should just rename the
modified page.
