That's most likely the cause of the 'freeze' that Steve Simitzis is
seeing. Technically all RPC2 applications suffer from this, but the Coda
clients and servers are actively using probes to detect dead
connections and destroy all rpc2 connections to a dead host.

Right, that would be my solution as well. Alternatively add all the
structures to a list (or array) and kill off the oldest connection
whenever there are something like 100 entries (maybe an auth2.conf
setting). We can assume that even for a very busy auth2 client, a
typical clog operation should take no more than a second or two.
