After adding all the native classes, you will need to add the classes that you
want to treat like native classes (listClass etc).

[ngeoffray, 2012/12/11 09:30:15]

Done.

Line before this should be unnecessary, since enqueueing the listClass will lead
to registerInstantiatedClass.

Removing this will mess up --disable-native-live-type-analysis, and the various
sets of classes.
The intention is to remove the 'enqueue all resolved classes' hack, so we will
need the native classes to progress through the stages unused -> pending ->
registered.

Please test with --disable-native-live-type-analysis.
