Compression reduces file size without losing entropy; in fact it serves
as an entropy concentrator. That said, I agree that its output is still
not small enough and its speed is unacceptable.

As for modifying kernel code,

$ cat /dev/zero > /dev/random

.... can swamp entropy harvesting. Its an obvious attack and easily
spotted/thwarted, but I'd like to defend against it; the current code is
a bit too naive.
