[bind10-dev] Thinking aloud: Receptionist

[Jerry Scharf]

A receptionist has a functional advantage that is allows the auth (or 
recursive) code to be upgraded without a server reboot. The new auth 
code version instances are started and go through their initialization, 
then the receptionist starts feeding the queries to the new instances 
and then the old instances are killed.

I do not know how important this feature is, just observing that it can 
be had with the receptionist.
