No thanks.  It's a waste of CPU cycle.

I prefer fvwm2.  ULE works fairly well.

I can assure you that the numerical simulations I run, along with
the "make worlds", and compilations of gcc's tree-ssa branch
stress the system.  I re-install over 100 ports today and the
load average was rarely below 5.  I was use linux-opera and
knews and sylpheed and several other program and noticed
nor degradation in responsiveness.  Does seti cause a problem
if you are not running X (or KDE).

If ULE is destined to be the default scheduler in 5-stable, then
we need to have more people test it.
