  "message": "Cache PerfCounters instance in PerfCountersMeasurement (#1308)\n\nThis patch fixes #1306, by reducing the pinned instances of\r\nPerfCounters.\r\n\r\nThe issue is caused by creating multiple pinned events in the\r\nsame thread, doing so results in the Snapshot(PerfCounterValues* values)\r\nfailing, and that\u0027s now discoverable.\r\nCreating multile pinned events is an unsupported behavior currently.\r\nThe error would be detected at read() time, not\r\nperf_event_open() / iotcl() time.\r\n\r\nThe unsupported benavior above is confirmed by Stephane Eranian @seranian,\r\nand he also pointed the dectection method.\r\n\r\nFinished this patch under the guidance of Mircea Trofin @mtrofin.",
