Tracks the current set of logical breakpoints.

<p>
Its assertions require perfection in the sequence of events: 1) No double-adds. 2) No
double-removes. 3) No extraneous updates. At the end of each test, the current set of
breakpoints in this listener should be verified against those reported by the service.
