No. The idea of a roundabout over a junction is that you shouldn't need to stop most of the time. Of course you should be prepared to if needs be, but the whole principle behind them is that traffic flows through them. Otherwise you might as well just have a junction and be done with it.
Doesn't make sense that. Traffic can't flow from all three entrances all the time to the three possible exits, it's physically impossible.
The actual idea of a roundabout is that no one route has greater right of way than another, as opposed to a T-Junction where one route has right of way over the second and the second over the third. All routes on a three way roundabout give way to one and are given way by another route.
