    A list which cannot be iterated sometimes.

    This is a C{list} subclass to get past the type check in L{send1msg}, not
    as an example of how real programs might want to interact with L{send1msg}
    (or anything else).  A custom C{list} subclass makes it easier to trigger
    certain error cases in the implementation.

    @ivar iterate: A flag which indicates whether an instance of L{BadList}
        will allow iteration over itself or not.  If C{False}, an attempt to
        iterate over the instance will raise an exception.

        Allow normal list iteration, or raise an exception.

        If C{self.iterate} is C{True}, it will be flipped to C{False} and then
