Reading straight through the file, that should be true.  I don't know
if it will be true in the case of raw seeking nearly to the end of a
file and trying to read past the beginning of the last page.  I think
that would possibly be the only case where it would not be true,
because it would not be possible to recapture the stream at that
point.
