	// A new Go-created thread with the same ID appears and

// goroutine or P.
//
// Callers can elect to pass a constant value here if the status is clear (e.g. a goroutine must have
// been Runnable before a GoStart). Otherwise, callers can query the status of either the goroutine
// or P and pass the appropriate status.
//
// In this case, the default status should be traceGoBad or traceProcBad to help identify bugs sooner.
