I think the problem is that you're only reading 4096 bits (bytes? No
idea), and iterating through that. I could be wrong.

List,
I was messing around with generator expressions. I tried to make a
script that would read a few bytes from '/dev/urandom' for eternity.
It then did something pointless like computing checksums and printing
them out. Unfortunately, the script only runs a few seconds and then
terminates. I'm n
