Yes, buffer is a page (well, used to be, I think it still is). No,
snprintf isn't available, but we don't need it -- we know the output
will not be greater than 10 character or so, so when we hit
(pagesize-SAFELENGTH) we stop.

what get tricky -- is making the data in the second page (for
continutation of the data) start at the right place.
