Yes, you can keep working. The trick here is that the export happens on
a clone of the Buffer (indeed, of the whole set of Buffers we're using),
so if you make changes it won't affect the current export.I think I could make this work if I could figure out a way to send a signal from the main thread to the background thread.... Richard
