Rebooting or shutting down. Before 1.3.81, I would occasionally get 
kernel panics at runtime, but no longer; on the other hand,  I don't 
leave my machine up long enough to necessarily reach that point. I 
reboot because AFS starts behaving strangely; I'll get contents of files 
that are incorrect, etc. I've used afs flushvolume at least once to fix 
that, but I don't know whether it's a consistent fix. In some cases, 
I've know that AFS had confused my machine because I'd get a bus error 
running gcc; I wish I recalled whether it happened only when compiling 
from source files in AFS space, or whether it was any invocation of gcc. 
That part isn't particularly reproducible, and I haven't until recently 
gotten fed up enough to commit myself to really tracking this problem down.
