Just a philosophical issue...
a) Return of malloc is never tested for NULL.
b) In this light id_to_name will free the memory allocated - but
never tests if null. free(null) might be considered unfriendly.
(qrtn.c)
c) malloc(0) will do different things on different platforms.
Sometimes it will return a pointer to valid memory, sometimes NULL, and
sometimes it will return a pointer to a random memory location which is
invalid. (I think A/UX did that)...
