[pacman-dev] download interrupt mechanism

Hi, working on a GUI frontend for libalpm, I noticed that download process lakes for an internal interrupt mechanism. Download cancellation is only handled by catching SIGINT signal. I think it would be a benefit for libalpm to have more correct download interrupt mechanism like trans_interrupt handle package transaction cancellation. I'm already working on a patch and I would like to know if you would interested in adding this feature to libalpm. Regards.
