Review comment:
@szlta , if for every new feature we add a new thread pool then the code
will become a huge burden to maintain. The RPC thread pool is meant for that
doing the stuff within thread of the pool that can be increased if needed. By
creating a new pool we are not changing anything just adding more burden from
code perspective. Same on the HS2I user will need to wait and see the result
of the command same with the purge.
