// Clearing the disk cache for one origin is served by two independent code
// paths: CacheFileIOManager::EvictByContextInternal() dooms the entries that
// still have an active handle, and CacheFileContextEvictor::EvictEntries()
// walks the index and filters everything else by origin. test_cache2-32 only
// ever reaches the first path, because its entries are still in the memory
// pools when the clear happens. Bug 1591362 was an inverted origin comparison
// in the second path, which deleted every entry except the ones that were
// meant to go.
//
// Restarting the cache leaves the entries on disk with no active handles, so
// the clear below is served entirely by the context evictor.
