I just pushed 3 fixes to trunk. Please try again with next nightly build and report the failures. I am not very confident about the result because libnuma may have yet another crazy behavior when it sees your missing NUMA node #1 (it exists but it's empty in my setup). Let's hope I can fix anything but this test, at least. Brice
