Subject: runtime: disable parallel for tests under race detector.
X-Git-Tag: go1.1rc2~1961

runtime: disable parallel for tests under race detector.
The race detector does not understand ParFor synchronization, because it's implemented in C.
If run with -cpu=2 currently race detector says:
 WARNING: DATA RACE
 Read by goroutine 5:
  runtime_test.TestParForParallel()
      src/pkg/runtime/parfor_test.go:118 +0x2e0
  testing.tRunner()
      src/pkg/testing/testing.go:301 +0x8f
 Previous write by goroutine 6:
  runtime_test.func·024()
      src/pkg/runtime/parfor_test.go:111 +0x52
