You are right, the "data structure threads", which we call servers, poll on requests in a busy loop. If your data structures aren't very busy, dedicating a thread to serving the data structures may not be a good trade-off, in which case you don't want to use delegation. Note, however, that a single server can host any number of data structures, core counts are growing rapidly, and hyperthreading doubles the number of available hardware threads, making the trade-off easier to swallow.
