Hi, Vince, I don't know exactly Pharo, but when you fork a process, it becomes an independent thread of work. So in that process you can send your async call and wait for a response and then do the work. All inside the forked process. It's the smallalk's scheduler that will take care of passing control to other available (green) threads So it's not clear from me what you need. If you have many forked processes, each one will do is work up to the end. No need to resume it from outside.
