I was mistaken, it was 4096kb.  So the actual byte count would always
stick at 32769b.

I tested out the readline methods, by replacing them with manual
readline statements, but the buffer just doesnt contain anything after
32769b, so i believe the problem is with the popen buffer not exceeding
32769b, but i have been unable to find any information as of yet to why.

Are there any python config files that would limit this? I looked in
popen2.py, but I found nothing.
