I think I figured out part of the cause. I have a bunch of logs here to
show how I came to this conclusion.
My best guess is that this basically boils down to an AFS consistency
problem. Note that in most cases, I've used best-tux.cs.wisc.edu as a
URL - what I suddenly realized was that this picks the least loaded
machine at the time of the query to connect to (which apparently changed
between commands). So all the bizarre behavior, I believe, was because
I was updating the repository on one machine and AFS wasn't consistent
when the next command ran on another machine. Perhaps someone else has
a setup like this that they can verify this behavior?
What still bothers me about this is that the initial commit that started
this all was about an hour before my attempt to check out.. and I've
never noticed propogation issues before, so things must be consistent
relatively fast. We've also used CVS extensively around here and have
never had a problem that I'm aware of. I've even been able to tell
people on the machine next to me to check things out immediately after
checking them in. I'm still somewhat baffled, but I think I've at least
identified a way to safely go about my work.
Anyway, logs....

** I get frustrated and start over. After toying around for awhile, I
notice that the commits/updates work when I specify a particular machine
