+The forked child will not get the same thread handle as its parent, it
+will get the thread handle from the main thread instead. The child will
+not terminate because the threadcount is still 2 after the fork (it is
+set to 1 in MTinterface::Init and then set back to 2 after the childs
+memory gets overwritten by the parent).
