In my case it's basically because I'm not using a conditional GET so there's 
no way for it to know whether anything's changed, not efficiently. A swap of 
a pointer under a lock just isn't worth worrying about by then.

Ok, that's a much more complex question that ties into the whole issue of 
metadata exchange, to which I will leave you in Ian's hands. I don't think I 
want to know how that sausage is made.
