 "OpenBSD::IdCache" provides four classes: "OpenBSD::UidCache" for UIDs,
 "OpenBSD::GidCache" for GIDs, "OpenBSD::UnameCache" for user names, and
 "OpenBSD::GnameCache" for group names.

 "UidCache::new" creates a UID cache, which can be used to look up user
 names by using the "lookup" method.  Looking up a numeric user name is a
 no-op. Non-existing IDs return a default value, which is normally "undef"
 but can be provided as an extra argument to "lookup".

 "GidCache::new" provides the same service for GIDs.

 "UnameCache::new" creates a user name cache, which can be used to look up
 UIDs.

 "GnameCache::new" provides the same service for group names.
