Issue #25

Please merge also 0e557a1

The previous was broken and the former one is cleaner

Thank you. Currently I can't decide if it is OK to not fail on bad credentials. If you can communicate with a pool but it rejects your password this perhaps should just be corrected or the server removed from the list?

I dont think failing to shell is good. Many miners may only be checked once a day. It should continue to do something useful. I think report the error and move on to next server is best. I could see someone starting the miner first then adding a new worker to pool. Or modifying credentials on pool before updating miners. Miner should always be doing something useful if possible.

How about bail out if only one server specified. Otherwise switch to backup.
Not sure what to do if both are NotAuth. Maybe add a counter and bail out if all servers fail?

I also think that failing to shell is always the worst option of all.

Most of miners are not human-checked more than once a day.

And it's a pity that your mine stopped working because of any error.

Actually as a workaround I wrap the execution of poclbm in a bash script that ensures that it will never end

while true; do
./poclbm [....]
sleep 60
done
