I can't find in the thread where removing byte arrays (meaning arrays of 
fixed-length non-unicode strings) was suggested -- though changing the 
dtype specifier for them was.  That is 'S' would change to 'B' in 
python3 (with some deprecation period for 'S'), and 'U' would remain 
'U'.  That seems acceptable to me, as long as we have some way to have 
fixed-length 8-bit strings.  Hopefully all the new chararray unit tests 
will help with this transition.
