For the same set of packages, etc on a 32bit box the memory size is
112MB.

It's due to how python does 64bit objects in memory - they explode about
2-3x the size.

James Antill has done some marvelous work reducing the overall memory
footprint of yum, but it's not going to overcome the 64bit issue above.

Unless there is a compelling reason like you're using > 4GB of ram, you
should think about running i686 not x86_64.
