I had to tweak the   if (writecnt > 5) {} clause to allow for the
larger size but other than that this Works For Me. It drops the
program time on my 128k part to 30 seconds.  Thats quite a bit better
than the 20 minutes it used to take.

I also verified that chunk sizes larger than 12 fail but I didn't try
any values between 1 and 12.
