I still don't think it is a good idea to allow to change primary proc behaviour
(allow/forbid secondary procs to attach) on the fly.
Imagine the situation - there is a primary proc (supposed to run forever)
that does  rte_thread_register/rte_thread_unregister during its lifetime.
Plus from time to time user runs some secondary process to collect stats/debug
the primary one (proc-info or so).
Now behaviour of such system will be completely non-deterministic:
In some runs primary proc will do rte_thread_register() first, and then secondary
proc will be never able to attach.
In other cases - secondary will win the race, and then for primary 
eal_lcore_non_eal_allocate() will always fail.
Which means different behaviour, significantly varying performance, etc.

I am not big fun to introduce such workaround at all, but at least startup flag,
will guarantee consistent behaviour: secondary proc will always fail to attach
and  eal_lcore_non_eal_allocate() will always succeed
(as long as there are free lcore_ids off-course).

From your previous mail:
> A EAL flag is a stable API from the start, as there is nothing
> describing how we can remove one.
> So a new EAL flag for an experimental API/feature seems contradictory.

Hm, yes there is a gap, but why eal flag can't also be an experimental one?
What will be the difference between flag and API call here?
We can still reserve the right to remove/change it at any time.

As another thought about startup parameters -
would it make sense to have new one: --lcore-allow-list=...?
That would limit lcore_ids available for the process.
Without this new parameter specified -
lcore_allowed_list would be equal to startup lcore list (static ones),
and no dynamic lcore allocations will be allowed.
As an example:
dpdk_app --lcores=6,7 --lcore-allow=0-100
will reserve lcore_ids 6,7 at startup (same as we do now),
and leave [0-5] and [8-100] available for dynamic usage.
