Okay, so have an option to turn it off, maybe even off /proc/sys... But
for most systems, I think it could enhance performance... As a general
rule, it strikes me there are alot of things we could do in the idle loop
rather than just idle. What about trying to defragment memory for
example, even if we didn't want to touch the disk for whatever reason?
Again, this could be disabled to reduce power consumption...
