I discovered this by putting a kDebug() << "Tile: " << this << ", " << 
kBacktrace() << endl; in KisTile::addReader(). When I create an image of 
10x10 pixels I don't get all that many tiles, so I was able to actually look 
at what happened, and I found that both the histogram and the layerbox were 
calling this method many, many times on the same tile.
