I have another approach that does not hit heavily on AF_RXRPC and DNS
resolver. So probably better to hold and judge the next version when
it comes out. Regardless, reviewing chunk processing independently
would help and it is pretty well benchmarked change too (with a test
that is publicly available).

It prevents workqueue lockups happening while not doing any significant
hits on throughput.
