   [testrunner] load tests concurrently into test execution processor
   
   loading every test up-front into the processing queue costs about 224MB for a
   x64 testsuite run.
   
   This CL eliminates that overhead by utilizing generators and threading.
   
   LoadingProc now loads test after receiving the results of the loaded tests.
