Otherwise, if there are any parallel tests, it will hang and panic with "all goroutines are asleep - deadlock!". Do not use flag.Uint to handle the error for us because we also want to error on N==0, and because it would make setting the default to GOMAXPROCS(0) more difficult, since it's an int. Check for it right after flag.Parse, and mimic flag errors by printing the usage and returning exit code 2. Fixes #20542.
