• VSCode Version: 1.13 insider
• OS Version: Windows

Steps to Reproduce:

1. clone vscode-eslint repository
2. chdir to eslint/eslint-server
3. open terminal (I use powershell as the terminal, not sure if it matters)
4. type npm install
5. type npm run watch
6. Kill the terminal by pressing the garbage bin button

Open a process explorer

Observe: there are still two process orphaned conhost.exe and node.exe
