How would you deal with non-reentrant functions (and their global data) belonging to the same library in all your three types?
And subsequent non-exported & helper functions internal to the library that could potentially modify those global data?
Library functions should be thread-safe by default because we are aiming at high performance which often means multiple CPU cores running multiple threads. Of course it is possible to make functions that are not thread-safe or reentrant, whatever your reason might be for doing so. A function with static data is likely to be thread-unsafe unless you take special precautions. My proposal allows functions to have a static data section that can be used for whatever you want. If you want multiple library functions to share the same static data then you can either put them into the same module or put labels on the data with public visibility.
