 * The rcache will be automatically expunged when the number of expired

 * of live krb5_donot_replays by EXCESSREPS. With the defaults here, a typical
 * cache might build up some 10K of expired krb5_donot_replays before an
 * automatic expunge, with the waste basically independent of the number of
 * stores per minute.

 * The rcache will also automatically be expunged when it encounters more
