        Only a single AsyncHTTPClient instance exists per IOLoop
        in order to provide limitations on the number of pending connections.
        ``force_instance=True`` may be used to suppress this behavior.

        Note that because of this implicit reuse, unless ``force_instance``
        is used, only the first call to the constructor actually uses
        its arguments. It is recommended to use the ``configure`` method
        instead of the constructor to ensure that arguments take effect.

        ``max_clients`` is the number of concurrent requests that can be
        in progress; when this limit is reached additional requests will be
        queued. Note that time spent waiting in this queue still counts
        against the ``request_timeout``.

        It can be used to make local DNS changes when modifying system-wide
        settings like ``/etc/hosts`` is not possible or desirable (e.g. in
        unittests).

        ``max_buffer_size`` (default 100MB) is the number of bytes
        that can be read into memory at once. ``max_body_size``
        (defaults to ``max_buffer_size``) is the largest response body
