Remove flush note retry loop The retry loop was intended to make sure that we flush the process, but the approach is very brittle. For one, user none isn't allowed to send notes at all which would cause this loop to get stuck forever. For now, flushing isn't going to work at all if you run unionfs under 'none'.
