I'm not sure I see this as a bug, as they are different fifos. If they 
were opened and read they'd likely have different contents, though it 
wouldn't be a good idea for diff -r to open fifos.

Perhaps the diagnostic message could be improved, though I'm not sure 
what the improved wording would be.
