Would it be possible to update the timestamp of preimage every time it is
used (e.g., in rerere.c:merge()), and check for that?

It would be _possible_, but we are _not_ modifying the file at that point,
so somehow that solution feels very wrong, no?

rr-cache is basically a static database. The fact that we have a file
named 'thisimage' is just an abuse - to put a temporary file somewhere.
Therefore, depending on lockfile infrastructure to change timestamps for
us while manipulating 'thisimage' should feel no less wrong, don't you
think so?
