All over freebsd we have cryptic XXX comments that have no meaning to
anyone except whoever wrote them (and, I suspect, no meaning to those
people either after a couple months have elapsed).

To the degree that XXX represents "possible trouble here" and/or "more
work to do here", I would argue that any placement of a new XXX
requires at least a sentence (and probably more like a paragraph) to
describe why it's there.
