Decommit the allocator is needed, becides, we need to stop the reader thread, which means we need to stop the IWMReader. And that's exactly what asf_reader_cleanup_stream() does. So maybe we could replace IBaseFiler_Stop() with asf_reader_cleanup_stream()?

I'm not sure if Pause() are necessary, the Pause() in the document is to restart the thread and start pushing data again. We have IWMReader_Start() which did this.
