Could it be that we are incorrectly merging the oneway street with the 
non-oneway street, making the non-oneway section oneway? What are the 
criteria for merging ways? I think that the merging should be blocked if 
any of the routing attributes differ: oneway, toll, mkgmap:unpaved, 
access/motorcar/bicycle/foot, etc.

In http://www.openstreetmap.org/browse/node/101581030 the node is not 
part of a turn restriction relation. If it were, that would be a further 
reason not to merge the ways, I guess.
