Ah, thanks, great stuff. I didn't realise the 'threads cannot be implemented in a library' standardization fix had got as far as this. I'd encountered bits of this (quick_exit()), but not realised why they were useful.
(And Paul's slides are the best explanation of the problem I've ever seen. Slide 26 is particularly good ;} )
