I fail to see how moving to a microkernel would have any effect on heavy disk usage effecting overall system performance. Maybe I'm overlooking something, but I see no inherent causality here. Care to explain your logic?

Microkernels can do hard real-time. Thus even *drivers* get throttled correctly so as not to chew up the system.

The problem is not "overall" system performance--that's throughput. The problem is "interactive" system performance--that's latency. Something which is rattling my disk should get throttled down when I am watching a movie. That movie should get what it requests up until it would hang the system. At which point, the system should pause it and throw an error/warning/etc. Any time I interact with the system I expect the computer to handle that stuff *NOW, DAMMIT*.

For servers, things are different. Throughput often matters more than latency.
