Koichi, can you please help. There are lines in a dump that are not referenced by anyone else. And these are not ROOTs. For example, I'm looking in my dump by address of object and there is no other objects which have references to this object:

```
$ ag 0x7fc4adc55a20 dump.json

1812949:{"address":"0x7fc4adc55a20", "type":"DATA", "class":"0xaf6c70", "struct":"proc", "references":["0x7fc4adc55a48", "0x7fc504140390", "0x7fc4adc55a20", "0x7fc5041404d0"], "memsize":104}
```

How can it be? Is it a dead object who got in a dump or am I missing something?
