Nick, you and some others seem to be arguing based on a totally flawed base, namely: - we can guarantee anything at all in the VM - we even care about the 16kB blocksize - second-class citizenry is "bad" The fact is, *none* of those things are true. The VM doesn't guarantee anything, and is already very much about statistics in many places. You seem to be arguing as if Christoph was introducing something new and unacceptable, when it's largely just more of the same. And the fact is, nobody but SGI customers would ever want the 16kB blocksize. IOW - NONE OF THIS MATTERS! Can you guys stop this inane thread already, or at least take it private between you guys, instead of forcing everybody else to listen in on your flamefest. Linus
