The multiqueue is the root cause of the disease.


It is impossible to have a light-lock producer-consumer problem, when
the data structures require you to lock ALL THE CPUS for (a) an extraction
decision, and (b) a extraction operation.

It should be one queue.

Computer science does not have light locking operations for the data
structures used by the code today.

I said this in Lousa.
