The exchange mechanism itself can be extracted into a channel object. We do so using busy-wait in 100% Prolog to extend the π-WAM emulator. To obtain channel objects, we could straight forward realize the offer/poll from Doug Lea’s SynchronousQueue using the Prolog dynamic database. The test case with emulated MPMC queues worked like a charm. We plan further benchmarking of physically grouped logical threads.
