[Glass] LargeObjectNode instances

[James Foster]

No, it is not expected that an instance of LargeObjectNode no longer responds to messages such as #asOop. Here is what I get in 3.6.2:

(Metaclass3 allInstances detect: [:each | each name asString = 'LargeObjectNode class']) thisClass allInstances any asOop “3546113”
