minimal reproduction case

Primary LanguageTypeScript

Reproduction steps

  1. Disable all extensions
  2. Run the "log hello world with an index 100000 times then sleep forever" task and wait for it to finish printing. It logs 100k times because it can take multiple hours of running a task like tsc --watch to echo to the console enough to visually witness the issue. It just gets us there quicker, but it happens no matter how you do it.
  3. Open both sample.ts and sample2.ts
  4. Close sample2.ts and reopen it about 10 or so times, waiting a few moments before closing it for VS Code to load the problems in the file and draw the red squiggle for the missing typescript package.
  5. Observe VS Code freezing for longer and longer each time you close sample2.ts until it eventually crashes the window process
