Just thought that the process item may change between runs, so I need to keep this as well.
I’ll work on it over the weekend

>>> When you say "I'll build a queue" do you mean for your project or adding it onto process_items?  As long as it was backwards compatible with the existing behavior of a process_item, it would be nice to add that onto the process_item so there is a standard way for anyone to push items onto a process_item queue instead of everyone implementing it their own way.

To test this I built a minimum reproducible case below where it launches a process that simply sleeps for 5 seconds twice in succession. As you can see from the print log, he first one gets killed.
