I am working with concurrent futures multiprocessing and I want to implement graceful exit on SIGINT while also killing all non started processes. This is achieved by the executor shutdown as shown in the code snippet. The problem is with the additional process that is spun up after the shutdown from the queue because of

There is Python code that contains a singleton_process decorator and a decodable hello function. The decorator is designed to protect against re-running the script in another terminal/process.

In the multiprocessing how can I know the status(like its running,killed) of current process and other process ?
