 // linked with browser_tests. The reason is that these are just unit tests, but
 // due to the static initialization of the UMA counters they have to run each
 // in its own process to make sure the counters are not initialized before the
 // test runs, and that the StatisticsRecorder instance created for the test
 // doesn't interfere with counters in other tests.
