Happens you do a ls -l in /proc, all the "special" files except for the pid
directories disappear. This happens to me after I've rooted around through
some of the directories, possibly something gets stomped on as the user cd's
through the new "modular" directories. The intentional feature of this is
allowing users to finally be rid of that kcore file I'm sure. :)

I cut these out of my syslog/messages file. I was in X windows when I did
it. I don't know what order they came in so they may not be in the
"standard defecate the bed" order.
