  14. >Exactly.  I would almost bet that it is some weird timing problem.

  16. That's where my money is.  Linux, the PD unix system, had quite a 
  17. few problems with race conditions within the filesystem code in
  18. earlier versions.  Each new fast processor that it got moved to 
  19. found more and more.  It wouldn't suprise me that the DLC does
  20. something (read some series of instructions) in a sufficiently
  21. different amount of time than the 486 does.  That would be enough.
  22. I wouldn't trust a company that can't remove such simple problems
  23. from its code.  Then again, I don't trust NeXT anyway. :)
