is CTRL-C in the remote screen that bad ?
with CTRL-C you can stop the miner or other scripts but you can not restart 3main or kill the screen as far as i know.
I do ctrl-C in the miner screen all of the time to restart it. I said kill the miner in my previous post, I just didn't say how. Either way, the watchdog detects low utilization and restarts 3main eventually.
