        The given random bytes source should return the number of bytes
        requested each time it is called and should probably not return the
        same bytes on two consecutive calls (although this is a perfectly
        legitimate occurrence and rejecting it may generate a spurious failure
        -- maybe we'll get lucky and the heat death with come first).
