Is there a reason why that's not included? Please enlighten. Thanks.

We shouldn't add it today because we don't know the license of the
Joyant patches, and someone must be the maintainer.  A bigger reason is
that this is a feature that can be added via a gem download.  Adding
interpreter probes cannot be done via gem download.

Maybe we will expose dtrace through ruby in the stdlib someday, but I don't
think we should today.
