At the same time, make it cancellable in the middle of loading

This was done, but the code went very complex for few, if any, real benefits.

In both (mono/multi-threaded) versions, we had to manually call Qt.QApplication.processEvents() to keep the UI responsive. It was therefore decided for now that it wasn't worth it, and we are back for now to a much simpler, mono-threaded version.
