Database dumps and loads (via krb_util, which is used by kprop) are
slow when the database is that big (apparently order n log n).  But
ticket requests (kinit) and database updates (kadmin and kpasswd) are
still very fast (apparently order log n).  Also, the ndbm files get
really big (I think I tested it on a Sun with 10,000 principals, and
the file was 5 meg in size), if this is a problem on your system.

A kprop/kpropd that sends only updates is critical for realms that
have # of principals in the tens of K.  In this case, kdb_util should
only be used in emergencies.
