it depends ... for small programs where you really *know* (by
definition) there really may only be one instance of that data, it might
be actually the better solution - in that case you know the working set
for sure (size of .data). This is the kind of programming where you also
rely on the OS (kernel, supervisor, container, ...) doing all post
termination cleanups.

Many Plan9 programs are written in that way - they're so damn small that
they just don't need much function local (or even dynamically allocated)
