This is a revised patch originated by Junji TERAMOTO for HEAD.
[BTree vacuum before page splitting]
http://archives.postgresql.org/pgsql-patches/2006-01/msg00301.php

I think we can resurrect his idea because we will scan btree pages
at-atime now; the missing-restarting-point problem went away.

Have I missed something? Comments welcome.
