// Assumptions for the compilation cache:
// - Files in the temp directory we work with can disappear at any moment, either some of them or all together.
// - Multiple workers can be trying to read from the compilation cache at the same time.
// - There is a single invocation of the test runner at a time.
//
// Therefore, we implement the following logic:
// - Never assume that file is present, always try to read it to determine whether it's actually present.
// - Never write to the cache from worker processes to avoid "multiple writers" races.
// - Since we perform all static imports in the runner beforehand, most of the time
// workers should be able to read from the cache.
// - For workers-only dynamic imports or some cache problems, we will re-transpile files in
// each worker anew.
