I'll gladly attach my sentiment to that.

I think that any typical scheduler such as present in either Linux or BSD
might not be fully optimal for DF given how we are switching major
subsystems to non-typical Unix ways of doing these.  It might be better to
check out microkernels and see how they also do this.

Of course, I could be totally off base, as happens from time to time (or was
that almost all the time?), and then my above statement is at value void.

Btw Matt, I am getting insane from the intr 5 livelocked! livelock removed
messages.  It floods my vty0.  intr 5 is my audigy and typically scores
around 80000-85000 Hz and drops back to 8000 Hz and up and down and up and
. ..
