Because eventlet, gevent and friends works *because* they have full
control over the event loop, and they can use greenlets as they like.

This is not possible with implementations like txwsgi (Twisted) and
ngx_http_wsgi_module (Nginx).

eventlet has support for Twisted, but, as far as I can tell, it works by
running the Twisted event loop inside a greenlet.
This is of course impossible with ngx_http_wsgi_module, since it is
embedded in a web server written in C.

Can you suggest a less intrusive extension that works with *every* WSGI
implementation?
