I have a small D function (C linkage) compiled to a shared object that
I am calling from Python via CFFI that works fine with no D runtime
initialization. Thus I have experimental evidence "always" is not
entirely the case! I really need to explore the boundaries of what
point you have to actually initialize the D runtime…
