Should this be back ported to v4? |

Looks like it makes the test flaky again, so at a minimum, I guess this should mark the test flaky again in |

@Trott I’d say its unrelated, thanks for pinging me on this, I’ll look into it. :) |

Running CI one more time mostly for confirmation of FreeBSD issue non-relevance: https://ci.nodejs.org/job/node-test-pull-request/3233/ |

Java exceptions on the pi1-raspbian-wheezy buildbots. Haven't seen this one before...
Since they were green last time, I'll land this later today unless someone disagrees. |

Disable stdio buffering, it interacts poorly with printf() calls from elsewhere in the program (e.g., any logging from V8.) Unbreaks among other things the `--trace_debug_json` switch. Undoes commit 0966ab9 ("src: force line buffering for stderr"), which in retrospect is not a proper fix. Turning on line buffering fixed a flaky test on SmartOS but the test wasn't failing on other platforms, where stderr wasn't line-buffered either. Mark the test flaky again, it failed once in a run of 333 tries on the smartos-64 buildbot. Disabling buffering should be safe even when mixed with non-blocking stdio I/O because libuv goes to great lengths to reopen the tty file descriptors and falls back to blocking I/O when that fails.

@thealphanerd Eventually, but let's give it a little time. I'd like to see it go into one or two v6 releases first, just to check if it doesn't break anything. |
