It is a feature that the objects that were fetched for a quick peek become
immediately unreferenced and eligible for early removal unless they are
kept somewhere, e.g. remote tracking refs. What problem are we trying to
solve?

I thought everybody agreed that the current expire window for unreachable
objects is way too conservative, especially given that the only purpose of
that window is to protect live objects from concurrent gcs. Perhaps the
only thing we need to do is to trim that window down to say 2 days or even
8 hours?
