LGTM, just one question about the case where we encounter a failure to create a ref for the JavaScript error in the Error ctor.

Should we cause a fatal error here to kill the process?

Probably. See also a few other places in this Error class where error-handling code can't throw errors.
We'd need a napi_fatal_error() API or similar.

I'll leave this the way it is for now. Fatal error discussion is at nodejs/abi-stable-node#232
