a central pacman cache
Signature files (files ending with .sig) are now cached just like ordinary package files. Previous versions of Flexo would serve .sig files via redirect and not store them on the local file system.
Flexo fetches a package from a new mirror if the previous mirror is still busy serving an earlier request. This is particularly useful in combination with Pacman's ParallelDownloads setting, because it can substantially increase your download speed if you have a high-bandwidth connection.
