A possible explanation for the infrequent CTDs we've been seeing since adding fast forward is that QWebChannel doesn't keep a reference to the python objects that it passes to js, so if the object is GC'd before the front end is done with it, it crashes. We don't really like QWebChannel anyway, so this begins replacing that with FastAPI.
