 // Returns an instance of a Backend of the given |type|. |path| points to a
 // folder where the cached data will be stored (if appropriate). This cache
 // instance must be the only object that will be reading or writing files to
 // that folder. The returned object should be deleted when not needed anymore.
 // If |force| is true, and there is a problem with the cache initialization, the
 // files will be deleted and a new set will be created. |max_bytes| is the
 // maximum size the cache can grow to. If zero is passed in as |max_bytes|, the
 // cache will determine the value to use. |thread| can be used to perform IO
 // operations if a dedicated thread is required; a valid value is expected for
 // any backend that performs operations on a disk. The returned pointer can be
 // NULL if a fatal error is found. The actual return value of the function is a
 // net error code. If this function returns ERR_IO_PENDING, the |callback| will
 // be invoked when a backend is available or a fatal error condition is reached.
 // The pointer to receive the |backend| must remain valid until the operation
 // completes (the callback is notified).
