Hello Eliot,

I am very inspired by the new Squeak 5.2 VM and its amazing speed! Just
dreaming of having Open Croquet working on it. And now after first early
steps of porting from Squeak 4.x, even without formal tests, it is seen how
much faster Open Croquet demos are working.

Actually, this fix is in adapting the IslandReader segment loading methods
to the new behaviour of '#primitiveLoadSegmentFrom: segmentWordArray
outPointers: outPointerArray': "Upon successful completion, the wordArray
will have been becomed into anArray of the loaded objects." In original
Open Croquet for Squeak 4.x,  'IslandReader>>#loadSegmentFromData:
segmentWordArray outPointers: outPointerArray' traversing the loaded
WordArrayForSegment with #nextObject for post-sending startUp message to
objects ('#startUpInIslandReader: reader'). But, in Squeak 5.2 it should
uses an array of the loaded objects, instead WordArrayForSegment object.
That's it.


Best regards,
Nikolai
