Did anyone manage to answer Richard's question?

I'd also like to port generate_tiles.py to use multi-threading. Since tile 
generate is naturally parallel in nature, it seems ideally suited, but the key 
question is... is Mapnik thread safe? i.e. Can I have one map object in Python 
and safely render from it in multiple threads?

Warren Vick

Subject: [Mapnik-users] Multi Threading

I've noticed that the generate_tiles.py script does not support multi threading.

Is there a way you can change the software to multi thread, so it can use 100% 
CPU instead of just the 25% mine is using?
