I might add that I suspect Ligfietser (=recumbent cyclist) is talking 
about cycleway roundabouts (or cycleways that circle a roundabout). Many 
of these (at least in the Netherlands) allow cyclists to take the 
roundabout in both directions.

So, yes, for cars roundabouts will be oneways mostly everywhere, but not 
necessarily for cyclists or pedestrians. I also note that the wiki 
tagging page suggests that oneway=yes is implied, so it follows that 
every non-oneway roundabout should be tagged oneway=no?
