I don't think there's any consensus for the approach you describe above. If
anything it seemed the least objectionable form was something involving
posix_fadvise or libaio.

Tom did wave us off from Simon's approach on the basis of it being hard to
test and Heikki seemed to be agreeing on the basis that it would be better to
reuse infrastructure useful in other cases as well. So I guess that's some
kind of consensus... of two.
