Since it happens inmidst a tape backup operation, one would assume
it's a WRITE.  The current timeout is 100 seconds.  That ought to be
enough one would think, but i can bump the value.  The odd thing is
that one out of perhaps a million commands crashes.  IMHO, different
commands are only issued at open/close time.
