// 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.
