SUGGESTION: download packages at once [solved]

Question

When pacman downloads packages, it downloads them one by one. It means:
1 - Connect
2 - Identificate
3 - set dir
4 - Download
It does this for each file. even if the server is down, it will try to connect again to the same server for each file it has to download.
My suggestion is that instead of downloading file by file, have it to download all files at once, just one connection per server.
This would avoid the connect and identificate in many of the files. It also would make much more easier to cancel an upgrade with Ctrl + C, cause it would be one cancel per server, not one cancel per file per server (in case you use wget).
And, of course, it would speed up the downloads.

Answer 1

-r: recursive
-l0: depth=0
The download function of pacman is programmed to check file by file. To apply a patch that uses single connection with wget (if wget supports it) the code should be cleaned a bit by putting the "check download" code in another function (before there was no need so it is was ok like it is right now), and there should be a way to specify in pacman.conf that your xfercommmand supports multiple files (%u single file, %U multiple files?)
