eventlet revert causes swift auth to hang

[Dan Prince]

I haven't put my finger on why yet but it appears that the eventlet changes in 6219f94b3a1103a16bd5f16ed8ffdd41a85280e1 are now causing my Swift -> Keystone connections in SmokeStack to hang. Reverting the commit fixes everything.

I have auth token configure like this:

[filter:authtoken]
paste.filter_factory = keystone.middleware.auth_token:filter_factory
signing_dir = /etc/swift
auth_host = 127.0.0.1
auth_port = 35357
auth_protocol = http
auth_uri = http://127.0.0.1:5000
# if its defined
admin_tenant_name = service
admin_user = swift
admin_password = SERVICE_PASSWORD
delay_auth_decision = false

I would like to suggest that we revert the eventlet commit until we figure it out:

https://review.openstack.org/#/c/28785/

A very safe thing to do at this point since it was the last commit.

See kerrin's stack trace on the original commit here:

https://review.openstack.org/#/c/28737/

This looks like the same thing I'm seeing in Swift:

ImportError: eventlet imported before keystone (env var set to None)
