There are zillions of invocation dispatchers registered with a multitude

of codes. Currently the unit dump that is done once every 15 minutes is
chock-full of one-off units. Let us report the short class name of
the dispatcher, rather than the code with which an instance is registered.

Also: Thou shalt always iterate over the entrySet of a Map if thou planneth
to utilize both the key and the value.
