Whenever I use cmd/trace, be it on:

* OS X laptop

* Linux GCE instance

* physical Linux host at my house (Ubuntu Xenial)

... I always get the "warning: low resolution timers are in use! results may be useless!" warning. (or whatever the exact wording is)

What does it take to get high resolution timers and no warning?

I can't find the message anywhere in the sources. What does print it?

In https://github.com/golang/go/issues/16247 Dmitry wrote "It's not harmful. Just ignore it."

It would be nice to hide the warning, though.
