This repo_config_get_ulong() call will look for the configset entry in a hashmap which is faster than parsing the configuration file from scratch every time, but still expensive for my taste in a function as hot as unpack_entry(). Should this also go in the_repository->settings instead? That way we have a single field access instead of a hashmap lookup (with multiple layers of function calls between us and the actual lookup).
