This is true, but the global object itself usually "lives" in an object, which you "normally"
need to free by means of the delete operator which in turn relies on availability of
the c-runtime.

Have a look at the current implementation of the thread_specific_pointer which calls
delete on the object to free the heap when the thread is done.
