Exactly. Right now, I use the oprofile experience as a reason for why we
should try to do this. But hey, who knows, in one year, maybe people will
use _this_ experience as a reason why we should never do it again.

We just don't know yet. But that's no reason not to try. Either way, we'll
hopefully learn something.

Or to quote Edison:
"I have not failed 700 times. I have not failed once. I have succeeded in
proving that those 700 ways will not work. When I have eliminated the
ways that will not work, I will find the way that will work."
