[Vm-dev] Move to Spur: how can I change WeakRegistry packages?

[Esteban Lorenzano]

Hi,

I need to change the WeakRegistry, to adapt Pharo to finalisation on Spur and I wanted to “star over”, injecting into Pharo the packages Collections-Weak and System-Finalizer from Squeak. 
Now, that breaks everything, of course :)

So, I wonder if there is a clean way to do this?

thanks,
Esteban
