Memory Policy Changes
There have been some pretty major changes to the way memory is handled in VisualWorks in the 7.7.1 release - and that means that there have been changes for ObjectStudio 8.2.1 as well, since it's built on top of VisualWorks. You should really have a look at the release notes for 7.7.1, and the class comments for AbstractMemoryPolicy. This visual of the new hierarchy makes it clear what's changed:
Class MemoryPolicy is mostly a "legacy" class now, and is not the default one in use. The default is LargeGrainMemoryPolicy, as internal testing in Cincom engineering indicated that it performed best in the widest variety of situations.
Your mileage may vary, of course - so again, have a look at the docs.
