Big Scary Software - python runtime, filesystems, etc

Mort (now at Nottingham) pointed us at some educational videos in the last couple of days

1.The Giant Interpreter Loop that python runtime uses is not really something that admits of concurrency, but also has a lot of weirdnes about it...
(sorry - as per comment - GIL = Global Interpreter Lock, not Giant Incense Lamp)

2. Making sure things really are written to stable storage or disk, as we used to call it, is really not quite as simple (or obvious) as you might think

3. not even on windows

I guess these should be like public health warnings, a bit like the German and French governments recent IE warnings
