It is a known defect and the fact it was not reproduce in the threaded
receiver is not an accident. Note in the real world it should not happen
or with other words do not expect an overloaded server to perform well.
I suggest to add this in the known issue list.

Nor did I suggest that it was, well done for doing it that way, Francis.

It can happen in the real world, and I suspect the more interfaces one
has the worse it becomes.? I reduced the rate of perfdhpc to 100 LPS,
and while the starvation was not as pronounced, it is still present:
Running: perfdhcp -4 -r 100 -R 500000 -p 5 178.16.1.10
