This still needs to be done. The patch needs to at least add an item
to TODO, BUGS, or ROADMAP here.

I just checked this and it looks fine to me. This comment should be
eliminated.

What does this mean?

And this?

This comment is actually just something pre-existing that I
noticed and not a bug in the new code in the patch. The new
screen_info stuff in Owen's latest patch could provide a safe way to
do this, but this should just be disappearing with the cache
rewrite. Fine to ignore for now.

So, given suitable answers to the items above, I don't see why this
patch shouldn't go in.
