-** The distinctive characteristic of this sqlite3_file is that the
-** actual on disk file is created lazily. When the file is created,
-** the caller specifies a buffer size for an in-memory buffer to
-** be used to service read() and write() requests. The actual file
-** on disk is not created or populated until either:
-**
-** 1) The in-memory representation grows too large for the allocated
-** buffer, or
-** 2) The sqlite3JournalCreate() function is called.
