sbws is just a normal tor client, with a custom controller.

We need some more information to diagnose the issue, and answer these
questions:

* Is this issue reproducible?

* Are all tor clients affected?
* If only some tor clients are affected, why are they affected?

* Are all bandwidth authorities affected, or just the ones running sbws?

* Are these issues actually instances of know sbws bugs?
