Yes, that's one way to do it. I'm happy as long as we can use it for both 
`TestDiagnosticReporting.py` and `TestProgressReporting.py`. I was on the fence 
about the broadcaster and listener being part of the utility, but I think it 
can work. The diagnostics are slightly different because they listen for two 
event types, but I guess we can abstract over that by ORing the types.

If we do go that route, I think we might want to make this a `TestBase` class 
instead that starts and stops the event thread at the beginning and end of the 
test. Something like `GDBRemoteTestBase` and `PExpectTest`.
