Miner restarts on `work` submission failure

[aolieman]

I still get regular ETIMEDOUT errors from Axios calling the RPC. When the network error happens while submitting work, instead of retrying the submission, the homestead server restarts the whole mining job.

Is this the intended behavior?

Here's an example from my logs:

}
