    Don't just close the profiler, stop "recording" first.

    I want to add that I mistakenly thought that closing the profiler stops "recording" but I'm getting mixed results. I find things run much smoother if I remember to stop recording before closing the profiler window.

    To get around the issue skewing our profiling, we're just automatically clearing the profiler whenever it gets into this state. You can do the same thing by sticking this in an Update() loop:

    if (UnityEditorInternal.ProfilerDriver.firstFrameIndex > 0)
    {
    UnityEditorInternal.ProfilerDriver.ClearAllFrames();
    }

    This seems to happen on the same frame that UnityEditorInternal.ProfilerDriver.firstFrameIndex becomes greater than 0, which reinforces the idea that it's a bug related to Unity accruing more profiler frames than it can hold in a single buffer.

    +1. On 2017.1.0f3, triggering when the window is full of samples and goes back to behaving when I hit clear.
