This will break my renderfarms, since each client are moving rendered 
tiles on a per layer basis (using the tilesathome.conf option 
LayerUpload=1) to a common upload dir, which a single upload.pl then 
processes every 5 minutes.

Currently I have 40K+ tiles rendered over the last 6 hours, awaiting upload.
