[Buildbot-devel] buildbot, docker, and the slave protocol

I'm trying to use docker inside a build run via buildbot.
(Not the other way around... this is a normal buildbot, no containers,
no nothing.)

The slave runs a shell step that builds a docker image
and intends to use it to run tests, but the job fails with messages like
remoteFailed: [Failure instance: Traceback (failure with no frames):
<class 'twisted.internet.error.ConnectionLost'>: Connection to the
other side was lost in a non-clean fashion.

This just happened, so I haven't really looked into it yet, but it kind
of feels like Docker is frobbing the network and making buildbot's
connection drop.   Shame buildbot doesn't have a stateless client protocol
lying around waiting for someone to test it.  (Does it?)
