Add pid to CompletedProcess object, which is returned by subprocess.run.

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

首先閱讀 subprocess.run 進入點及其回傳的 CompletedProcess 物件。追蹤子程序的啟動與回收方式，包括平台特定的行為。當 subprocess.run 一致地回傳已完成程序的 ID，且涵蓋率驗證了新屬性時，即表示完成。
