What about tracking the entropy and only returning a certain number of
bytes.  read() could just start returning "" when it runs out, or it
could raise an exception.  Perhaps there should be multiple levels of
support; at the minimum level only available() and new() are
supported, and the object only supports read().  Higher levels could
then define additional methods for checking how many bytes are left.
