Summary: Previously, the network stack `communication::Server` accepted connections and assigned them statically in a round-robin fashion to `communication::Worker`. That meant that if two compute intensive connections were assigned to the same worker they would block each other while the other workers would do nothing. This implementation replaces `communication::Worker` with `communication::Listener` which holds all accepted connections in one pool and ensures that all workers execute all connections.
