- Add ServiceIdZone interface for getting temporary ids.
- Add RingServiceIdZone which uses the isolate's object id ring.
- Add GrowableServiceIdZone which uses a growable array.
- Unit tests for ServiceIdZones.
- JSONStream has a service id zone.
- Default service id zone is ring with eager id allocation.
- All service RPCs can include a _serviceIdZone parameter.
- Value of _serviceIdZone can be Ring.NewId or Ring.ExistingId.
- All ObjectIdRing usage in object.cc has been replaced with `jsobj.AddServiceId("id", *this);`
- Add a policy for id reuse to ObjectIdRing::GetIdForObject
- ObjectIdRing can dump its contents to JSON.
- Add _dumpRingRequests RPC which dumps the isolate's ring.
- _getCrashDump includes complete object id ring.
