Philip,

Thanks for this report. I've not had a chance to run the threaded version on windows but I've also not heard of any success either.

I think writing in support for multiprocessing, as tobias mentioned, is a good idea to look into. As well as perhaps keeping single threaded support around as an option in that script.

Has anyone used the current threaded version of generate_tiles.py on a Windows machine?

The old single threaded version still works fine for me but attempts to make the threaded version run have failed on two different machines running Windows XP. It generates a few directories and populates them with a few tiles but then just stops processing after a handful of tiles. Both machines are dual-core and I have tried setting the max number of threads to 1 and 2 (and also 4 to see what would happen) with no obvious change.

Any encouragement welcome...
