BUT I've tried to make it with current master into my local but it fails because 'restart' always work fine. It looks only until 0.7.3. Generally, this code doesn't a problem anymore in current master and branch-0.8, but this kind of synchronized blocks don't look good. I prefer to change it but it's not a bug now. What do you think of it?
