As of 1.3.73 (or around there) and up, running portato gives a very high
load in my opinion. Bloats my "xload" :) I stopped running it a few days
ago when I discovered that. I like the util otherwize, and if it could be
implemented somehow so that it doesnt use as much CPU time, I'd appreciate
it. I'd say the load rises by 0.2-0.5 when starting portato. When you "ps
-ux" it, or use "top", it doesnt show as using a lot of CPU, so I dont
know why the load averages go up as much.

Just seems to me it would benefit from being put into the interrupt
handler, and reading the load averages from within the kernel structures.
Would probably be just a few lines of code run every jiffy.
