Will do so.

Maybe another solution, but don't know if this is useful.

First, splitter reads relation, ways and nodes. So I think after these 
three steps it should be possible to have all problematic objects with 
all ways and nodes.
Then check for all nodes, in which tile they would be and save this 
information to the problematic ways/relation, they belong to.

Afterwards start normal splitting and if splitter check a problematic 
object, then stop splitter writing it in normal mode and instead write 
the hole object to the tile. If the order of the splitted tile isn't 
important, you can also look for each object, if it is in problematic 
part. If so, skip this object (node, way, relation) and write these at 
the end of the (node, way and relation) block.

Don't know if this would be faster.
