Okay, so, for OSM terminology, a roundabout means 1) traffic goes in
one direction; 2) entering traffic must yield; and 3) entering traffic
need not stop (no stop signs).

I hope not...OSM currently has no way of reflecting priority at 
junctions. Introducing this distinction just for "circular junctions" is 
a bit pointless.

However if the consensus is to distinguish between the priority rules at 
"circular junctions", I hope it will be explicitly tagged (e.g. 
junction=traffic_circle) so mkgmap will still be able to recognise a 
"circular junction" and call it a roundabout even if it doesn't comply 
with the OSM semantics for one.
