This is a bug in dht it seems like. It is stripping PHASE1 flags
unconditionally.

(gdb)
1212                    DHT_STRIP_PHASE1_FLAGS (&local->stbuf);
(gdb) p local->stbuf.ia_prot
$18 = {
  suid = 1 '\001',
  sgid = 1 '\001', <-------
  sticky = 1 '\001', <-------
.........
}
(gdb) n
1213                    dht_set_fixed_dir_stat (&local->postparent);
(gdb) p local->stbuf.ia_prot
$19 = {
  suid = 1 '\001',
  sgid = 0 '\000', <-------
  sticky = 0 '\000', <-------
...

This is leading to 7777-->4777

Will update bug with same info
