Yeah, the normal use case when you're doing images is that you're going
to end up displaying it.  And `image-size' has to render the image to
see how big it is, so during normal usage, having `image-size' cache the
image is a big win.

Hm...  Perhaps `image-size' should just have a DONT-CACHE optional
parameter?

No, you've got overcommit on Linux, so you often don't get a NULL when
you need it...
