**Statutory Warning** Scraping tiles at full speed is unethical and harmful for the whole community because you can very well crash the server, or dump high "extra-bandwidth" costs on the tiles provider and possibly bankrupt the very people who were helping you. Highly recommended that you use a controlled mechanism, like a download manager, that downloads tiles in a queue instead of all at once, with some time delay, or with a VERY tight control on bandwidth (like 10KB/s or something). You don't REALLY need to get it all in 20 mins, even if your internet bandwidth theoretically says so. Give the tiles downloading exercise a whole night, and we can all work together in peace.
