Global Lock when copying Trefs with multiple threads

ROOT
10

Note the example in reported might be over-simplified. If it is not oversimplified, then upgrading the Derived class so that:

        Event(const Object* object) {
            TRef ref(object);
            for(int i = 0; i < 25; i++) {
                charges_.emplace_back(ref);
            }

works would solve the problem (i.e. adding a constructor in Derived that take a TRef as an argument.

PS. Or even further :slight_smile:

        threads.emplace_back([object = std::move(object)]() {
            TRef ref(object.get());
            for(int i = 0; i < 100; i++) {
                Event event{ref};
                event.run();
            }
        });
