Incoming mail makes a pong, from kmail, and I believe that was still 
working albeit with a hoarse voice, I'd assume because the machine was 
pegged out.  And as of this morning, only 2 copies are seen and everything 
is working nominally.  It looks like killing the one clear at the bottom of 
the htop listing when sorted by cpu%, may be the reset key. Killing all the 
cpu hogs, which took about half an hour because it was often 30 seconds 
after sending the top one a signal 9, before htop would recognize another 
F9 click.  cpu usage didn't fall below 99% until there were only 3 hogs 
left on this 4 core box.  Killall came back clean on the first call, then 
couldn't find any more to kill, while I still had most of a screen full 
according to htop.

Each was using about 13% of a cpu when I started, and as I killed them, the 
remaining ones just increased their usage.  When I was down to one, it was 
still using 100% of the core it was on, but was bouncing from core to core.

If it means anything, the running kernel is a BFS enabled kernel, a major 
increase in interactivity compared to CFS.  Sweet.

Could that be a clue?

Cheers, Gene
