However, they cannot determine whether they should free all memory during shutdown to mirror the behavior of Ruby when RUBY_FREE_AT_EXIT is set. This ticket proposes a new API called rb_free_at_exit_p that returns true when RUBY_FREE_AT_EXIT is set, and false otherwise. -- https://bugs.ruby-lang.org/
