Yeah, that's what I saw on 10.1 as well.  It seems 10.2's installation 
didn't tune the hard drive, so that was where I started.  I'm thinking 
maybe run it under gdb and break into it when it starts going nuts and 
see what's going on.  Could be hit and miss, but if I can get a good 
stack trace, that might help me at least identify which file is corrupt.  
I know it's not cache, because I clear that on exit.

I like that - I can move files back singly as necessary to identify the 
problem file, assuming it behaves sanely when a clean .pan2 directory is 
there.

Not even hitting the swapfile.
