Symlink loops cause 100% CPU

Steps to Reproduce: 1. Clone latest systemd source code 2. Build the project with tests enabled 3. Observe 100% CPU on the VSCode main process The problem seems to be that the systemd build process creates a "fake" /sys file system with many symlinks. There are loops in this structure, and it appears that VSCode ends up iterating through the structure in and endless loop. If I delete the "fake" /sys directory, the CPU usage stops. I'd expect VSCode to be able to detect symlink loops quickly and abort iteration.
