Yes, I know it (indeed I've read it previously to write my post).
But according my own benchmark (using postmark tool) the performance of
'load' it's the same as 'round-robin'.
So, I tend to view 'load' algorithm (even in this current
implementation) as a kind of 'secure round-robin' for a servers with
high I/O.

He's so busy. I hope he could read this message in list.
