Not yet. :)
If the community decides that the VM should support this finalization 
mechanism and the VM maintainers add it to the VM, then we can load the 
rest of the (possibly updated) image-side code and have much faster 
finalization (O(1) instead of O(n) cost).
But if there's no decision till the release of Squeak 4.2, then we will
remove it from the Trunk before the release. Until then it's a good 
reminder IMO.
