Static route fails to serve byterange on Meinheld

[vytas7]

Apparently, setting resp.stream to a file-like object without a file descriptor (i.e., without a .fileno() method, such as a pure Python wrapper implementing .read()), fails in Meinheld with a TypeError.

I am of the opinion that Meinheld's behaviour is in direct violation of PEP 3333 on the matter, and filed this as a bug: mopemope/meinheld#130.
However, since Meinheld is one of the fastest ways to run Falcon, we probably need to decide whether we want to patch this on our side, document as a known limitation, or take another action (please suggest).

Personally I think we could just document this case. As an alternative we could provide a different implementation but I think it would be better to make it configurable by the user and not activating it automatically when running under a wsgi server
