Looking at errors for monotonic lib, I can find other references around github:
https://github.com/nameko/nameko/issues/533
https://github.com/eventlet/eventlet/issues/401

Swift-proxy indeed depends on eventlet:
root@juju-29125a-0-lxd-15:~# dpkg -l | grep eventlet
ii python-eventlet 0.20.0-4 all concurrent networking library - Python 2.x

And then the issue described at: https://github.com/eventlet/eventlet/issues/401 applies.

Moving back to Xenial seems to stabilize swift proxy.
