That very well may be. I haven't thoroughly checked but I think that even we are
 doing the right thing when we use TSC as a timecounter.
But at this moment I am looking for a quick/simple and "sufficiently good" fix
for the bigger problems with DTrace timestamping (kern/127441).

Another side of the "simplicity" is that the timestamp function for DTrace needs
to be fast and should not itself be probed.
