Matthew can you explain how you achieve atomic loading?
I thought that what I would do is:
- create an new SystemDictionary
- compile the code to this new namespace (not sure that this is easy)
- then if nothing wrong happen, add the new name to Smalltalk.

I am fixing bugs in a new loader for Monticello that does code
loading in a truly atomic fashion: code is swapped into the
system, and pointers are revised in exactly ONE primitive. I
have it working well enough that I made it my default loader.
It is able to load problematic packages that are sensitive to
inconsistencies during loading, like Monticello and Morphic.
As an Acid test, I am able to load Monticello using the new
package loader, which has, until now, been impossible in any
version of Monticello. The biggest remaining issue is Traits
support; Packages with traits are not supported.
