Also, perhaps I wasn't clear. The example program does not underrun repeatedly when PulseAudio is not running. It may underrun very occasionally causing a single pop, usually only immediately after running it.
When PulseAudio is running, as soon as it underruns once, the load caused by PA opening and closing the sink causing another underrun to happen instantly, and so on. And it goes into a loop it cannot recover from, leading to the flickering.
