When loosening a pack, the current pack_id gets reused when checkpointing and the import does not terminate. This causes problems after checkpointing as the object table, branch, and tag lists still contains pre-checkpoint references to the recycled pack_id. Merely clearing the object_table as suggested by Jeff King in http://mid.gmane.org/20160517121330.GA7346@sigill.intra.peff.net is insufficient as the marks set still contains references to object entries. Wrong pack_id references branch and tags lists do not cause errors, but can lead to misleading crash reports and core dumps, so they are also invalidated.
