When running multiple tests while not having any packages cached on the system, the multiple instances of Typst can accidentally clear directories for packages another instance has just created, leading to ghostwrites. See typst#2739
While this is technically a Typst issue, it arises mostly when running typst-test in its current form.
This will be resolved with the coming rework, which will ship its own Typst world implementation.
