Resume scraping

[philogb]

I'm trying to get all messages from a mailing list, but sometimes in the middle of the process I get a timeout. How hard would it be for the scraper to have an option to resume from last error? I mean, some of the files are there already, no need to refetch them.

I'm sure it's possible, but I don't know how easy it would be. I haven't looked at the code for years myself I'm afraid.
