Unlike with preemptive threading, a coroutine does not run concurrently with the rest of the program, but rather takes control until it voluntaril...

Typing Confluence

We investigate con uence properties for concurrent systems of message-passing processes, because such properties have proved to be useful for a variety of applications, ranging from reasoning about concurrent objects to mobile and high-speed telecommunication protocols. Roughly, con uence means that for every two computations starting from a common system state, it is possible to continue the c...
