we should test that a failure from one of the shared dirs will not prevent
progress (currently if one fails the tailer will not catch up).

> You can configure and run with multiple shared edits dirs but we don't have
> any test coverage for them. In particular, we should cover the behavior of
> the edit log tailer with multiple dirs, and failure scenarios (eg can we
> tolerate a single shared dir failure if we have two shared dirs).
