Then if we can +persuade a full repack to find A from one pack and B from the other, that will +give us a cycle when we attempt to reuse those deltas. + +The trick is in the "persuade" step, as it depends on the internals of how +pack-objects picks which pack to reuse the deltas from.

Any objects with a delta relationship must be present in the same + pack (i.e., no "--thin" packs on disk), so we will find all related objects + from that pack.

Picking the next pack to examine based on locality (i.e., where we found + something else recently). + + In this case, we want to make sure that we find the delta versions of A and + B and not their base versions.
