I use it for "manual" memory handling of Python objects.
Each time the WSGI application iterator yields a string and writing this
string to the clients returns NGX_EAGAIN, I push the object in the queue.
When writing to the client returns NGX_OK, I pop and deallocate all the
objects in the queue.
So far, this is the best solution I have found for this problem :).

No, I do not need this.

No, the queue is just a data structure.
Not sure to understand.
