[pacman-dev] download interrupt mechanism

[Guillaume Benoit]

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.
