I think you could just use ProgressMonitor as is. I think the problem is that the comments around that class and several inherited classes that have `Impl` in their name are confusing: the idea was that this class be abstract, but it turned out to be fully functional as is, *I suppose*. Could you try that and let me know how it works out?
