This is intentional.  The swap file uses pages of 4 Kb.  There are at
least two pages, mostly three: the first page with info about the file
being edited, the second page is the top of the tree structure
administration, the third page is the first data page.

The pages could be made smaller, but then I/O becomes a lot less
efficient.  It's a space-speed tradeoff.
