Pass along the PROVIDER type, that is already passed to AsyncWrap, along to BaseObject to set the handle_'s class id. This will allow all Persistents to be transversed and uniquely identified by what type they are using APIs such as v8::PersistentHandleVisitor.

For anyone wondering about possible performance implications, I haven't been able to measure any difference at even the nanosecond level of any micro-benchmarks. |

There was a problem hiding this comment.
Can I suggest you call it class_id? p_id leaves the reader guessing.

LGTM with a suggestion. |
