I just tried out the above patch against rev xx51. It does solve the 
problem of ways not displaying on multipolygon=outer (like the "other" 
patch v2 does) but also did not add some bizarre boundary lines that 
otherwise span some tiles.
On the other hand I could not find any place where polygon ares were 
rendered differently.

Many places correctly rendered with mapnik/osmarender (like the large 
multipolygon forest (inside a relation) East of Vienna is still not 
correctly rendered).
