// that the download we've started has finished, with minimal details about
// how it finished which aren't described in the API (and which internally
// are not entirely useful, either -- mostly unuseful nsresults). How
// do you signal the difference between "this download failed" and "all
// downloads failed", particularly if you aim for API compatibility? The
// code in nsApplicationUpdateService only determines the difference *after*
// the current request is stopped, and since the subsequent second call to
// downloadUpdate doesn't start/stop a request, the download listener is
// never notified and whatever code was relying on it just fails without
// notification. The consequence of this is that it's impossible to
// properly remove the download listener.
//
// The code before this patch tried to do the exit after all downloads
// failed but was missing a QueryInterface to work; with it, making sure
// that the download listener is removed in all cases, including in the case
// where the last onStopRequest corresponds to *a* failed download instead
// of to *all* failed downloads, simply means that we have to try to remove
// that listener in the error page spawned by the update service. If there
// were time and API compat weren't a problem, we'd add an onFinish handler
// or something which could signal exactly what happened and not overload
// onStopRequest, but there isn't, so we can't.
