AutoRTFM is designed to make it easy to take existing C++ code—which was never designed to have any transactional semantics—and make it transactional just by using an alternate compiler. For example, AutoRTFM enables you to write code like: void Foo(){    TArray<int> Array = {1, 2, 3};    AutoRTFM::Transact([&] ()    {        Array.Push(42);        // Array is {1, 2, 3, 42} here.        AutoRTFM::Abort();    });    // Array is …

In an earlier blog post, I reported that the memory usage of a small byte array in Java (e.g., an array containing 4 bytes) was about 24 bytes. In other words: allocating small blocks of memory has substantial overhead. What happens in C++? To find out, I can try to allocate one million 4-byte arrays …
