The final GC should be a major one
The final GC should be a major one

We do a final GC before shutting down the system, to clean up.
However, we were doing an ordinary GC rather than forcing a major GC,
so especially when the allocation area is large, this final GC could
be expensive.  This is really just a bug - the final GC should have
virtually nothing to do, because there is nothing live.
