I see; does it make sense to reset to false inside `check_gc_overhead_limit` so that callers of `set_should_clear_all_soft_refs` are in the same scope? (Other callers of `set_should_clear_all_soft_refs` always invokes it in pairs.)

If this reset-to-false occurs in the destructor as in your PR, who sets it to true for Parallel or other GCs?
