Previously es_unix would always try to get 16K, then return. Now it

tries to get an amount cooresponding with the size of the output buffer,
specifically 128 times the output size. So, assuming we have enough working
sources, each output byte will be the XOR of (at least) 128 bytes of text
from the output programs. (Though RLE may reduce that somewhat)
