Yes, I saw later how the magic token was used and clearly we do not
provide a mechanism for a program to determine which shared objects it
has been linked with. It would be nice if there were a dl* function
which allowed one to learn more about the shared objects...
so_map *dlinfo(void *handle, char *symbol)
ie, like dlsym() but returning the so_map ptr. Bad data hiding I know
