mod_wsgi has a similar feature.
If there is a request body, the handler is called only after the entire 
body has been read.

Moreover Python supports generators:

This means that the iteration can be suspended when nginx is busy 
sending data.

In a future revision I will had an extension, so that the WSGI 
application can voluntarily suspend its execution.
