Bug#534752: Acquire::http::Dl-Limit ignored when downloading from multiple sites

[jidanni@jidanni.org]

Package: apt
Version: 0.7.21

When apt-get or aptitude downloads from more than one server at once,
it ignores Acquire::http::Dl-Limit.

No matter if one uses
apt-get -o Acquire::http::Dl-Limit=11 --download-only
or mixed in
APT::Default-Release "experimental";
APT::Cache::AllVersions false;
APT::Clean-Installed false;
APT::Get::Purge true;
APT::Install-Recommends false;
Acquire::http::Dl-Limit 15;
Aptitude::CmdLine::Always-Prompt true;
Aptitude::Purge-Unused true;

My sources.list is
deb http://ftp.tw.debian.org/debian experimental main contrib non-free
deb http://ftp.tw.debian.org/debian unstable main contrib non-free
deb http://ftp.tw.debian.org/debian-multimedia unstable main
deb http://emacs.orebokech.com sid main

Screen shot:
Get:1 http://ftp.tw.debian.org unstable/main debian-reference-en 2.33 [824kB]
Get:2 http://emacs.orebokech.com sid/main emacs-snapshot-el 1:20090626-1 [12.4MB]
17% [2 emacs-snapshot-el 4978354/12.4MB 40%] [1 debian-reference-en 547870/824kB 66%]       30.6kB/s 14min 26s

However, after downloading several files, it will indeed start obeying
Acquire::http::Dl-Limit. So the problem isn't for the entire download session.
