In the process of initiating multiple processes concurrently, specifically with
automatic detection of the primary process, certain race conditions have been
identified. This patch series introduces a straightforward test that showcases
the issue and subsequently addresses the problems surfaced by the test. These
fixes aim to ensure the robust and secure utilization of DPDK within intricate
solutions that involve starting processes with job orchestrators such as Slurm
or Hadoop YARN.
