Thanks; apparently our mails crossed...
I suspect that in a sane repository with set of reasonably packed objects,
we can cheaply get a rough estimate of the number of objects to about an
order of magnitude (e.g. "likely to have 10k to 100k objects"), and we
might able to come up with a way to automatically raise the default
length.
