On Ruby 3.4 and later, we can exclusively use RUBY_FREE_AT_EXIT and disable most of the heuristics. This removes some of the limitations of the heuristics and makes ruby_memcheck more accurate. This feature could cause more false-positives, so there is an escape hatch by passing `use_only_ruby_free_at_exit: false` to the configuration.
