I think they were suggesting using a http proxy application - maybe
haproxy - will have more options to protect network resources from
misbehaving clients than the swift proxy application. Like kicking
off keep-alive connections after a while, or slow clients that hang up

That's cool, do you use round robin dns or something?

If we can reproduce the problem you're seeing there's some chance we
could offer a solution through just a code change, but it's going to
be difficult if repro requires haproxy in the pipeline. If there is a
problem w/o haproxy, it might have more to do with eventlet.wsgi or
python's base http server than swift... can you affirm the issue when
clients talk directly to the python/eventlet/swift application?
