Increase ``io.DEFAULT_BUFFER_SIZE`` from 8k to 128k. Adjust :func:`open` on
Linux to use ``max(io.DEFAULT_BUFFER_SIZE, device block size)`` rather than
the device block size. Improve I/O write performance by up to 5 times.
Increase ``io.DEFAULT_BUFFER_SIZE`` from 8k to 128k and adjust :func:`open` on
platforms where ``fstat`` provides a ``st_blksize`` field (such as Linux) to use
``max(io.DEFAULT_BUFFER_SIZE, device block size)`` rather than always using the
device block size. This should improve I/O performance.
Patch by Romain Morotti.
