--threads=x for x>1 results in no response bodies ever being served

Reproduction recipe: WSGI application:

"""Support for running hgweb as a WSGI app inside spawning."""
import os
HERE = os.path.dirname(__file__)
from mercurial.hgweb.hgwebdir_mod import hgwebdir
application = hgwebdir(os.path.join(HERE, 'hgweb.config'))

hgweb.config, which should be in the same dir as the wsgi application:

[extensions]
highlight=

[paths]
/ = /Some/path/with/several/hg/repositories/*

Run spawning, with actual output after attempting to load one page:

[imladris:~/Programming/spawnhg] augie% spawning spawnhg.application --reload=dev --port 9000 -i 0.0.0.0 --pidfile=spawning.pid --processes 2 --threads 4

But the response from the server never arrives. Checking with cURL indicates that the response headers are served but the body never arrives:

I'm wondering if this has anything to do with wsgi app support, my use of Spawning with threads is when using the django_factory.

Will investigate when I get some time (hopefully this evening)

It occurs to me that this might be related (somehow) to a generator response that isn't getting iterated properly.
