If you build a ChromeOS image for daisy using the LLVM compiler, load the image
onto a daisy Chromebook and try to run the Kraken telemetry test on that
Chromebook, it hangs.  GCC-built images do not have this problem.

python
/var/cache/chromeos-cache/distfiles/target/chrome-src-internal/src/tools/perf/run_benchmark
--browser=cros-chrome --remote=chromeos2-row5-rack4-host6.cros  kraken
