Fwiw, here's how I convert a crossroads into a roundabout in potlatch:
1) Break one of the roads where it joins the roundabout.
2) Start a new way at the break, click on the entry points of the other
three roads, then back to the first road, forming a sort of diamond.
3) Press "t" to convert the diamond into a circle.
4) Press "r" to repeat the description of the first road onto the roundabout
way, and add "junction=roundabout".
5) In turn, visit each of the roads, splitting them at the roundabout point.
6) Delete all the interior roads.

It's a bit clicky but it doesn't take tooo long.
