- transpute 9y agoHere is one from 2005: https://www.google.com/patents/US20060182137 https://www.google.com/patents/US20060182137 "An asynchronous message passing mechanism that allows for multiple messages to be batched for delivery between processes, while allowing for full memory protection during data transfers and a lockless mechanism for speeding up queue operation and queuing and delivering messages simultaneously." Maybe there are older patents that have expired?
