I didn't observe the test case explicitly, but I did observe in my own test
that I ran that it goes with the fast path, or I can't get a huge speed up.

Meanwhile my own test is only using 2M huge pages, and I can observe
interruptions of huge page sendings frequently.

But yeah let me try to capture something in this test too, at least to make
sure the standalone socket is being used.  Covering of huge pages might be
doable but obviously requires host privileges, so I'll leave that for later.
