Comment(by arma):

 {{{
    memset(addrbuf,0,sizeof(addrbuf));
 -  dest_addr = (struct sockaddr*) addrbuf;
    dest_addr_len = tor_addr_to_sockaddr(addr, port, dest_addr,
 sizeof(addrbuf));
 }}}

 looks fine, but Nick may prefer (for readability) to actually remove the
 first time we assign to it, rather than this time. I'll leave that up to
 Nick.
