I would recommend threading. You can run your GUI event loop on one
thread, and your network I/O loop on another thread. Both threads
spend the bulk of their time blocked on I/O, and you've limited
yourself to a finite number of threads (as opposed to a pure threaded
approach with every download is run on a separate thread), so resource
consumption should be reasonable.
