Want, so much. Use case: https://github.com/rack/rack/blob/rack-1.1/test/gemloader.rb
Hoe could do with something similar, and that would be well served by the above feature. (Note: the reason is that rack-master and rack-1.1 have different version dependencies)

Totally, I mentioned to evan the other day that I'd really like to strip this down as much as possible, and maybe even keep the minimum required details in a single marshalled file, in order to massively speed up boot times when loading gems. My spec.files patch made a 75% reduction in ram usage, but we can go a lot further, deserialization is expensive.

If time is available to do anything, do you want it in topic branches? is it safe to branch from master, or would you prefer them be based off the 1.6 branch?
