Basically, openssl was feeding uninitialized memory to the random number generator as seed
data, and this was generating warnings in valgrind and other memory checkers. This was
disabled, which silenced valgrind. Unfortunately, it also served to deplete the amount of
entropy available to the RNG. Of course, the question that others have raised is awfully
interesting: Is there really that much entropy in uninitialized memory to begin with?
