Describe the bug

The fake virtual modules plugin rely on a folder (node_modules/.rspack) that is shared between multiple compiler instances when they are run in the same context (base directory).

The issue is that this directory gets deleted as soon as the first build completes even though there could be one of more virtual files used by the other pending builds.
