        exceptions.RuntimeError: Request.finish called on a request
after its connection was lost; use Request.notifyFinish to keep track
of this.

it leaves things like the following in the web interface...

publish	vyhn2bb6iv6yqvp3scqwn3prtu	No	810B	70.0%	Sending Shares: 7

publish	klb2npqonmkfijkocz6wlip2ue	No	586B	30.0%	Sending Shares: 3
placed out of 10, 2 messages outstanding

the messages just sit there and don't seem to do anything to complete,
though when I run a check and repair everything appears to be okay.
