The test for profiling of channel blocking is timing dependent, and in particular the blockSelectRecvAsync case can fail on a slow builder (plan9_arm) when many tests are run in parallel. The child goroutine sleeps for a fixed period so the parent can be observed to block in a select call reading from the child; but if the OS process running the parent goroutine is delayed long enough, the child may wake again before the parent has reached the blocking point. By repeating the test three times, the likelihood of a blocking event is increased.
