The purpose of an event device is to do dynamic load balancing across

requirement of having unique, non-overlapping, core masks works against
or even defeats this purpose.
[VV]: I don’t understand your last sentence. Suppose I am having multiple
packet processing processes (each with a single thread and polling a disjoint
set of queues) and each linked to DSW. Each process would invoke the enqueue
which will be handled by the DSW linked to that process. Will the DSWs across
these processes "collaborate" to get load balancing across the processes?
Also, if you care about security, you don't want to disable ASLR.
That said, I can't see any immediate reason why it wouldn't work.
