By the way, I'm going to follow up with another PR that adds an add-on regression test. |

LGTM. I'll benchmark the difference between setting that generic callback. |
This reverts commit 3c44100. Reverted for breaking node-heapdump[0]. AsyncWrap assigns a class id but does not set a v8::RetainedObjectInfo provider callback with v8::HeapProfiler::SetWrapperClassInfoProvider(). The result is a null pointer dereference when taking a heap snapshot. It can probably be solved by setting a generic provider callback inside the AsyncWrap constructor but that may have performance ramifications that need to be investigated first. I move to revert it for now. [0] https://github.com/bnoordhuis/node-heapdump PR-URL: nodejs#1827 Reviewed-By: Trevor Norris <[email protected]>

Reverted for breaking node-heapdump[0].
AsyncWrap assigns a class id but does not set a v8::RetainedObjectInfo
provider callback with v8::HeapProfiler::SetWrapperClassInfoProvider().
The result is a null pointer dereference when taking a heap snapshot.
It can probably be solved by setting a generic provider callback inside
the AsyncWrap constructor but that may have performance ramifications
that need to be investigated first. I move to revert it for now.
