Oww, ECC RAM is better. Now, the idle process doesn't have to *test* memory,
but can now *scrub* it. Scrubbing is reading in data and writing it back out
(if you feel like it). Reading it should be sufficient. When the null process
performs a bad read, an exception handler gets called. The exception handler
spits something out to the error log, corrects the erronious data (if
possible), and exits.

Really nice process.

Cheers,
