 // Serialized object header encoding is as follows:

 // - VM object (from VM isolate): (object id in vm isolate | 0x3)
 //   This valus is serialized as a negative number.
 //   (note VM objects are never serialized they are expected to be found
 //    using ths unique ID assigned to them).
 // - Reference to object that has already been written: (object id | 0x3)
 //   This valus is serialized as a positive number.
