Here's an updated patch. It's the same as the original, but merged with
the changes to the vacuum_cleanup API you committed, and some comment and
space fixes here and there.
To-do:
* release pin earlier after reading the page, as discussed
* allocate memory for markpos/restrpos only when needed
* calculate a more precise estimate for the maximum number of items on an
index page
Not big things, but I don't have the time to work on them at the moment.
