Object>>#clone looks like an optional-implemented primitive that
does a #shallowCopy, but without the fallback-to-smalltalk that #shallowCopy
performs.  Not sure why those are both in the image.

I'd stick with #copy unless I was the implementor of the class being
copied, and even then, I'd make copy "do the right thing". :)
