test case

I am attaching a (reduced as much as I could) test case. It seems like we hit
this assertion when going back to a page that has been removed from the page
cache, but only after scrolling one of the pages, and only if one of the pages
has frames. Some of these may actually not be necessary, but those were the
conditions we could reproduce the crash more consistently with. We use 3 pages
as the page cache limit; raising that limit to 5 makes this specific test case
for the crash not work, which indicates it only happens when going to a
non-cached page.
