From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx> When trace-cmd stream is finished, the trace_or_sleep() will exit before waiting for the pipes to flush. Call trace_stream_read() one more time, and with indefinite blocking, as the pipes should finish everything and then close (which will stop the polling).
