Review comment:
I do think you see my point, by adding this new pool what are you actually
unlocking/unclocking ?
Which Threads/actors are blocked and how this is helping?
When you say HS2, can you explain what is blocked there and how that have an
impact on the system ?
What am trying to say is that there is nothing to really unblock and this is
adding some code that is not needed IMO.
