	We use weak linking to ensure we clean up at exit time correctly. If libc is linked, then we call our cleanup function by registering an atexit callback with the library. If libc is not linked, we have a weak symbol that results in a noop. Similarly, if we call rt·exit while linked with libc, this immediately calls libc's exit (which will call our cleanup as we registered it). If we are not linked to libc, exit() is given as a weak link to a noop function.
