// Captured before any test can install fake timers, so this yield always
// uses the real timer. Suites made of synchronous spawnSync tests can keep
// a worker's event loop blocked for the whole file (>60s), which makes
// vitest's fixed 60s worker->main `onTaskUpdate` RPC timeout fire and the
// run exit 1 with every test green. Yielding between tests releases the
// loop so the RPC response is always processed in time.
