This is a great idea.  I made a little proof of concept example here:
http://tinyurl.com/2zl9ar

There are some minimal comments that explain it.  Basically, the
example defines a new type of consumer (tracking_call_consumer) for
which the connect operation will register the connection object with
the consumer.  It then implements a simple class (tracking_consumer)
which is a tracking_call_consumer and will disconnect (from all
registered producers) once it has received a specified number of
signals.

Something like this will be a good addition to the library - when I
get more time I'll try to figure out a good way to integrate it with
the existing components, so that any component can be made to track
connections to its consumer ports.
