        This is primarily to rule out the memory BIO code as the source of
        any problems encountered while passing data over a L{Connection} (if
        this test fails, there must be a problem outside the memory BIO
        code, as no memory BIO is involved here).  Even though this isn't a
        memory BIO test, it's convenient to have it here.
