Well... CHUD is gone. I was running my usual group of applications while online, such as Safari, Mail, iChat and iTunes.
I went into the kitchen to get a cup of coffee and came back to find my computer frozen up.
The particular way it was acting is something I have never seen before. It sounded almost like a skipping music CD repeating a faint clicking sound.
The CHUD installer comes with an un-installer.
It works great!
