   // and keeps it running through the lifetime of this test. This is done to
   // avoid flakiness in restarting the server while the port is still in use.
   // If -1 is passed for |port|, a random number will be used. This is
   // recommended when possible, in case multiple tests are running at the same
   // time. For some tests this isn't possible though, because they use resources
   // that hardcode a specific port.
