Don't get me wrong, but I would expect an option with "global" in the
name to make the streams really global, not "sort-of-global" (;
Otherwise it looks like a half-baked-hack to fix just some particular
problem instead of looking at the whole picture.

There are two things involved here. The FILE objects and pointers to FILE objects. The stdio, etc. are pointers. These pointers are thread-local. The FILE objects are global and are used for the initial values of these thread-local pointers. If you want to get rid of the thread-local pointers, then you probably need a new configuration option.
