Description

Feature or enhancement

Proposal:

Some processes create *. files in the filesystem, thus it might be useful to know the pid of the completed process when the user needs to process these files after termination of the process.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

Research direction

Start by reading the subprocess.run entry point and the CompletedProcess object it returns. Trace how the child process is launched and reaped, including platform-specific behavior. Done means subprocess.run returns the completed process ID consistently and coverage verifies the new attribute.
