I think we've been at that discussion before, and eventually agreed there's no point why sei() should imply a memory barrier. I forgot about the details though, it's been a number of years ago. Anyway, it might make sense to provide an additional macro like __memory_barrier() that expands to __asm__ __volatile__(""::"memory"). -- cheers, J"org .-.-. --... ...-- -.. .
