    Memory leak in mountd
    
    In client_compose(), free() the hostent structure returned before
    exiting. Normally, gethostbyaddr() returns a pointer to a static
    struct, but this hostent comes from either get_reliable_hostbyaddr() or
    get_hostent(), both which return a pointer they privately xmalloc()ed,
    which thus can and should be free()d.
