+If one user (via SVN or otherwise) deletes or moves a page while another user 
+is editing it via the web, bad things happen. This patch addresses this by
+failing gracefully, and allowing the user to commit a new file with the same 
+name if desired.
+
+The patch is [here](http://ikidev.betacantrips.com//patches/disappear.patch).
+It requires a strip level of 4 -- sorry about that. --Ethan
