This makes sense.  Our KDCs use KDB and have no performance issues
whatsoever even though we have a respectably large plant.

We did, however, use up -w for ``inetd wait mode'' which I submited
as a patch a while back.  We find this feature quite useful as it
allows us to use xinetd's features to start different KDCs on
different ports and IP addresses with different configurations.
