Description

OS: Ubuntu 18.04 LTS
VS Code version: 1.44.2
Extension version: 0.27.0

The extension appears to be writing a lot of data to the disk very quickly, for reasons I can't figure out. My projects usually only contain a couple of files that are a few KB in size, yet when I make the slightest edit, save, or do just about anything the extension writes a lot of data to the disk. After about 20 minutes of usage, it has already written over 1 gigabyte of data.

Is this normal behavior or is something wrong? What's causing all those writes?

Research direction

No file, test, or entry point is named. Reproduce the excessive disk writes with Ubuntu 18.04, VS Code 1.44.2, and extension 0.27.0 while editing and saving a small project, then trace which extension activity causes them; done means identifying the cause and preventing the unexplained write volume.
