Dunno about that, but here's a possibly related datapoint. I reported
to Ingo yesterday that I was sometimes losing control of my GUI (KDE)
under heavy IO. I just reproduced it in mainline rc7. If I start a
bonnie, and click around popping windows to the foreground, then poke
KDE's menu button, I may lose all GUI capability for a _very_ long time.
Here, with bonnie, that means until it gets past writing with putc, and
moves on to rewrite. Ages.
