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").

Never trust an operating system you don't have sources for. ;-)
