mind; modifying the object, e.g. updating commit->parents list,
in-core by revision traversal machinery is very much within the
scope of its intended uses.

the contents from the result returned from the function (instead of
reading from .buffer), and free the memory when they are done?
That would be a fix that would be very much isolated and easy to
