System Information
Operating system and graphics card
Win 7 gtx 550ti

Blender Version
Broken: (example: 2.69.7 4b206af, see splash screen) Hash: c963488
Worked: (optional) Hash: 3c45fdd My own back up build

Short description of error
Selecting a mesh in object mode and in pose mode stores more than 100mb per click in files that are bigger than 200mb

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

Open Franck (blend file) franck_sheep.blend
Start to click select (no need to move your mouse), notice how the memory increases.
On my side when i reached the default 32 undo-step i m having more than 3 GB of memory allocated. Compare to hash 3c45fdd
Go to edit mode and click select again and notice how the memory is decreasing.

It seems like some Linux user couldn't reproduce it but i did reproduce it in so many windows machine even on a 32bit machine.

i guess my problem is related to that here (or should i make a different report?)

the problem is even worse with many multires objects (3-5gb per klick :/) heres a video demonstration -> youtube
its very easy to replicate just add a few multires objects and switch between the layer
