Let X bre a Huge Amount of Memory (tm) taken by said image, and Y be A 
Couple Kilobytes (tm) used by scaled down version
Your proccess: 
- Initially using X memory
duplicate image -> now using x * 2 memory.
scale image down, with UNDO active -> using x * 2 + Y memory 
discard copy-> back to using X memory.

My proccess:
- Inittially using X memory
- Disable Undo for this image
- Scale down: Using Y memory.
- Save copy
- Revert: Using back X memory.

As you see, they are roughly equivalent, exepct that your method, in 
the intermediate steps, use twice as much memory.  The slowdown 
complained about is probably due to Tile swapping . 

Take your conclusions.
