In a subsequently-posted Red Hat bugzilla, it's been clarified that
the systemtap data is of an undetermined format, so terminal output
would not be advisable.  So ignore that suggestion...

Also, my understanding is that this extension will be part of the
systemtap package, given that the manner of accessing the data
may change over time based upon the version of systemtap.

Thanks,
