I've now done that - which brings the time for test_SeqIO_index.py
down for Python 3.x to roughly the same as Python 2.x (about a
four fold speed up).

Under Windows there may also be a slight speed up for Python 2,
while on Linux/Mac there could be a slight slow down. I expect we
can work on this.

The good news is this yet another step towards supporting
Biopython under Python 3.
