I have now also committed 0002 and 0003. I made some modifications to
0003. Specifically:
- I moved has_lpdead_items inside the loop over blocks instead of
putting it at the function toplevel.
- I adjusted the comments in lazy_scan_prune() because it seemed to me
that the comment about "Now scan the page..." had gotten too far
separated from the loop where that happens.
- I combined two lines in an if-test because one of them was kinda short.
Hope that's OK with you.
