That would be better. But whenever I test things like this, I get
compulsive and run it so many times that I exhaust the entropy pool,
and then my read() of /dev/random just sits there. I'd be curious to
know if you have any clever thoughts on replenishing the entropy
pool quicker without losing much security.
