Squid crashes on shutdown while cleaning up idle ICAP connections.

The global Adaptation::Icap::TheConfig object is automatically
destroyed when Squid exits. Its destructor destroys Icap::ServiceRep
objects that, in turn, close all open connections in the idle
connections pool. Since this happens after comm_exit has destroyed all
Comm structures associated with those connections, Squid crases.

This is a Measurement Factory project.
