Did not investigate, but this test always fails on my laptop.
Tried multiple times, I caught one instance when the test was still burning
cpu after 5 minutes and I killed it.

Usually, it fails like this:

[dmarchan at dmarchan dpdk]$ ./master/app/test -c 0x1f -n 4 --no-huge
EAL: Detected 8 lcore(s)
EAL: Detected 1 NUMA nodes
