An LRU cache with deferred (on-request) writing. When values put back into
the cache, they are flagged as dirty, but are not written to the backend
until ``.flush()`` is called. When the cache is flushed, all dirty values
will be written back. Note that ``.flush()`` must be called frequently
enough that the cache does not self-evict dirty values--this will fail.

This is NOT thread-safe.
