I know very little about this. So a couple of questions:

- How do you see it is a longjmp across threads?
- Is this a longjmp out of a windows callback?

- Are longjmp between threads on w32 allowed? (A web ref would be good.)
- Same question for longjmp and callback. (Or do you mean long-jump in
a more generic sense there?)
