-------------------------------------------
Changes look good. Thanks for testing the upgrade path. This is a good thing
to fix, and you've covered all the bases, but I have a bad feeling that
something will break with this change. Only one way to find out, though. :)
+1 from me. I'll let this one sit a little while before I commit so that folks
have a chance to comment.
