Unshareable objects should not be touched from multiple ractors
so ObjectSpace.each_object should be restricted. On multi-ractor
mode, ObjectSpace.each_object only iterates shareable objects
even if running on the main ractor.

This proposal was confirmed.
We need to introduce same filter for some other methods...
