That's not the case that matters (to me at least).  If the input is a
file, we have a much better way of "guessing" the size than guessing and
growing -- just ask for the size.  Sure, we might need to make
adjustments if the file is changing, but there is always a better
measure than any statistical analysis.

To some extent this seems like a solution in search of a problem.
Growing the buffer exponentially is simple and effective.
