The thing is, the raw perfcounters interface isn't going to be useful as
is. And I have seen where things go when you split them up. So when I get
the choice, I'll go down the road of unproven failure, in the hope that it
will be successful, rather than doing the same mistake once more.

And I'm not insane.

Anyway, feel free to disagree. I just don't care.
