Unit test is failing:
DPDK:fast-tests / threads_autotest      TIMEOUT 600.01 s

It is seen in only 1 target (maybe the failure occurence is random):
  Debian 11 (Buster) (ARM) | PASS
  Fedora 37 (ARM)          | PASS
  CentOS Stream 9 (ARM)    | FAIL
  Fedora 38 (ARM)          | PASS
  Fedora 38 (ARM Clang)    | PASS
  Ubuntu 20.04 (ARM)       | PASS

I need to send a v4 with new implementation and better comments.
The Unix sleep will be upgraded from 1 ns to 1 us in case it makes a difference.
