+// Haiku implements the image_info struct and the get_next_image_info()
+// functions to iterate through the loaded executable images. The
+// image_info struct contains a pointer to the start of the .text
+// section within the virtual address space, as well as the size of
+// that section. All the read-only segments of the ELF-binary are in
+// that part of the address space.
