The scheduler is being improved for better behaviour on complex
topologies like multi core + NUMA and multi level NUMA systems.
If Con's work had gone in first, then conversely these improvements
would have had to wait.

What's wrong with that? The slowdown is due to the workload
becoming disk bound. The reasons are still not entirely clear,
but I don't think it is a recent (ie. 2.6) regression (or even
a regression at all IIRC).

And what QA would you have preferred?

I think if you are resorting to bringing up all time favourite
blunders when trying to justify Reiser4 being included, then
that is a sign right there that something is fundamentally wrong
(if not with the code, then with your line of thought0

And note my email has nothing to do with any *real* argument for
or against R4.
