tell Jens. He goes about fixing it all, not just the most visible pieces
that showed how much the Linux block IO code sucked. And guess what? His
patches are being accepted, and the Linux 2.5 block IO code is evolving
rapidly. Sometimes keeping broken code around as an incentive to fix it
*for real* is better than trying to massage the broken code somewhat.

a patch penguin doesnt solve this particular problem, by definition he
just wont fix the block IO code.

any other 'examples'?
