This was a symptom I used to see back when I had the serious troubles with softupdates that would routinely take down my systems under silly things like make world or untarring a large tarball. I don't see them anymore, and I exclusively use IDE here at home due to the ever-popular $$$ issue. :-) I used to be able to predict when the system was about to hang -- the disk would go wildly and, like you describe, all processes would momentarily stop, as if interrupts were all being overridden or something. However, I honestly don't see it anymore, and I don't exactly have spectacularly powerful systems (my most-thrashed box is a P90 with a 3.7GB). Still, back when I had these problems, I was one of the few. So I'm hopeful for you that someone can track down what you're seeing.
