It is always prudent to verify "sample" mode with "avgt", because timestamping overhead/accuracy
might skew the results in "sample".

Note that there are lots of timestamps, which would probably be problematic with multithreaded runs.
After http://hg.openjdk.java.net/code-tools/jmh/rev/cde312963a3d promotes to released version, it would
be much less of a problem.
