97 ia32 packages on an amd64

[Nuno Magalhães <nunomagalhaes@eu.ipp.pt>]

Greetings,

I know with the latest changes came a new APT that can handle both 32
and 64 packages, which is great. However, i barely need 32bit packages
and yet i have 97 ia32* packages installed. Most of them are libs, but
i also have ia32-at-spi, ia32-gtk2-engines, ia32-gtk2-engines-pixbuf
and ia32-xaw3dg installed.

The only 32bit app i use, barely, is Skype. I occasionaly compile
stuff for i386 with -m32 but it's not a necessity.

I also noticed that even though i have only two servers on my
/etc/apt/sources.list, apt is updating from three servers and there
are a whole bunch of files under /etc/apt/sources.list.d/, including
many ia32*.

The question is: how can i keep ia32 stuff to a minimum?

TIA
