Build does not wait for files to save

Issue Type: <b>Bug</b> In order to be able to run my code, I have to modify file:///proc/sys/fs/inotify/max_user_instances first. So I did and I told **VS Code** to run. This file, however, requires privilege escalation to be saved. Here is the order of events: 1. Ask me whether to escalate. 4. Build my code. 5. Run my code. 2. Get root password. 3. Save the file. Here is the expected order of events: 1. Ask me whether to escalate. 2. Get root password. 3. Save the file. 4. Build my code. 5. Run my code.
