Surely when isolation is something that will be configurable through
cpuset, it will become interesting. For now it's probably not worth
adding hundreds lines of code if nobody steps into such issue yet.

What is probably more worthy for now is some piece of code to consolidate
the allocation of those MSI vectors on top of the number of housekeeping
