Can't automaticly quit python language server after quitting VSCode on macOS

Bug: Notebook Editor, Interactive Window, Editor cells

Steps to cause the bug to occur

1. Open a ipynb file in VSCode
2. Close tab or VSCode after finish using it
3. You can find Microsoft.Python.LanguageServer still in the background, and can be seen in the Activity Monitor.app

Actual behavior

When I finished using jupyter notebooks in vscode, I close the window, press cmd+q to quit VSCode. However, there is a process called Microsoft.Python.LanguageServer which can be seen in the Activity Monitor.app, and using my memory more than 1G.

Expected behavior

When close all of the jupyter notebooks tabs in vscode, the Microsoft.Python.LanguageServer in the background should be automaticly quit.

@Saafo while I can’t replicate this exact issue, I do think I see a possible code path where this could be a problem. We’ll discuss this in our triage meeting.

Triage: The refCountedLanguageServer is only getting disposed when VSCode is shut down, not on notebook close. Looks like the monaco component is supposed to handle this, but I don’t see it happening. It should get closes on VSCode close, but that is timing dependent.

Year old bug, closing for now. @Saafo, please reopen if this problem still occurs when using notebooks in VS Code Insiders.
