I ran out of time to commit the first patch today. Perhaps I will get
to it over the weekend. If not, it'll be at least another week or so,
since I have a work trip all throughout next week.

Attached is V31, which is intended only to fix bit rot against the
master branch. There are some small differences, but they are hardly
worth mentioning.

The only thing that's slightly interesting about V31 is that the
"Limit get_actual_variable_range leaf page reads" patch appears
earlier now (as 0002-*). I plan to make that one into a standalone
patch, with its own CF entry, once 0001 is merged. I'll then discuss
it on a dedicated thread (and stop including it in future revisions of
the index prefetching patch set).
