* - We need to know which VM the containing object is in, so we can

|
29 |
*
|
|

30 |
* - We need to know whether the object is an array of refs (which
|

* includes dictionaries) or a struct, so we can properly trace and
|
|
|
32 |
* relocate the pointer to it from the change record during garbage
