Thanks.

Another question.  While there mightn't be much benefit to
implementing tracepoints natively as far speed of data collection is
concerned, having a consistent u/i and capabilities native vs remote
might be reasons to warrant a native implementation.  Anyone have any
thoughts on a native implementation?
