Here's a reference http://patterndigest.com/patterns/Observer.html
For our case the RealSubject is an shlib-unload. solib.c doesn't need
to know who is interested in this, just that there is something.
Conversely, the breakpoint code, doesn't care about the course of events
that lead to an shlib-unload, just that it occured.
