Does this actually wait for the download to complete, or wait until it's been
able to determine that the navigation is going to be a download?

Now that you have the per-URL map and are using it, could you just set up the
TestFileErrorInjector once and bypass all of the
ClearFoundFiles()/ClearErrors()/AddError() stuff?

No, because we're reusing the same URL and injecting different errors each time.
