Crypto.Util.randpool.RandomPool will silently operate even if it is seeded
with little or no entropy, and it provides no prediction resistance if its
state is ever compromised throughout its runtime. It is also not thread-safe.
This wrapper augments RandomPool by XORing its output with random bits from
the operating system, and by controlling access to the underlying
RandomPool using an exclusive lock.
