I've found that I got roundabout errors when people created multipolygons
with junction=roundabout - that tag was transferred to the synthetic ways
of the multipolygon, which then overlapped with the real roundabout.  I
generally fixed that by deleting the multipolygon - a roundabout is a
joined line, not an area.

Looking at the data, this is not what's happening.  Rather, I suspect
the opposite: when building the synthetic polygon, all the tags are
being gathered from the 'outer' ways and added to the area.

Anyone who understands multipolygons better than me care to elaborate?
