Memory usage gradually climbs when navigating through a pdf. I'm not sure if
this is a bug or a design feature (i.e. cache each page for fast rerendering),
but it causes problems on smaller memory machines.

With a long pdf consisting wholly of images, mupdf uses hundreds of MB of ram
when navigating through the pages.
