// require us to write to a file. An in-memory sqlite database is much faster
// than an on-disk database, so this can result in significant speedups in our
// unit tests.
// An InMemoryDirectoryBackingStore cannot load data from existing databases.
// When an InMemoryDirectoryBackingStore is destroyed, all data stored in this
// database is lost. If these limitations are a problem for you, consider using
// TestDirectoryBackingStore.
