Thanks for sending the patch Mattias - Coverity flagged me too, was intending on
having a look with colleague Sean here today - instead we'll review your patch shortly.

The delays were introduced so thread-spawns in the CI have some time to take affect,
and to (intentionally) introduce some jitter so we cover all cases of one-thread-before-the-other
checking poll counts and correct behaviour; this is useful as service-cores is inherently racy in
terms of things running in parallel, hence the service_dummy() function has the delay.
All this to say, lets leave the rte_delay_ms() in.

Expect a response (hopefully Tested/Acked-by) soon! Regards -Harry
