Oh, and after I sent it out, I wanted to look once again, and realized
that the "remove_myself_from()" function is entirely broken.

The caller has already removed the page entry, we don't want to remove
it again, we want to add a *new* one with us removed from it.

So here's an updated 2/2 patch with that fixed.

Let this be a lesson in just *how* little tested, and *how* crap that
patch probably still is.
