I think you are right, and there may be some other trouble spots in that
file too. I remember thinking that the code depended heavily on never
having a partial block at the end of the file.
But is it worth fixing? The only way I can see for the file length
to become funny is if we run out of disk space part way through writing
a page, which seems unlikely...
