Description David Woodhouse 2006-09-01 12:48:57 EDT
Our userspace sucks. It keeps waking up to poll things it really doesn't need to.
We should strive to be _entirely_ event-driven, as much as possible.

Constant wakeups will screw power consumption -- especially once we have the
kernel timer tick eliminated so we're actually waking the CPU for each userspace
stupidity.
