Well, sgminer doesn't have "no stratum" and "no getwork" parameters. Actually, turning stratum off seems to me like a bad idea, because even though the local server will be using long-polling, typically there will be other pools defined in sgminer.conf that are able to use stratum, which is useful because the local server will know faster that a new block has been discovered, in case any of the other pools detects it first.

Anyways, the local server should at least be seen as alive by the miner, even if the miner is unable to connect to it for whatever reason.
