We were profiling the loading of code that uses many Traits. We saw something like this (this is a tally for `TraitedMetaclass>>#addAndClassifySelector:withMethod:inProtocol:`):

From what we saw in `TraitedMetaclass>>#addAndClassifySelector:withMethod:inProtocol:` a method is first��added to `localMethodDict` and then it calls the super method that adds the selector to the `methodDict` of the actual class in `Behaviour>>addSelectorSilently:withMethod: `. Because of this we basically get an overhead as a method is added to two method dictionaries and adding a method to a MethodDictionary is slower, as it does operations like `flushCache` and `cachePragmas`.��

Should��the��`localMethodDict` also be an instance of MethodDictionary or could��it be a simple��dictionary?��

Cheers,
