** This file contains code use to implement an in-memory rollback journal.
** The in-memory rollback journal is used to journal transactions for
** ":memory:" databases and when the journal_mode=MEMORY pragma is used.
**
** Update: The in-memory journal is also used to temporarily cache
** smaller journals that are not critical for power-loss recovery.
** For example, statement journals that are not too big will be held
** entirely in memory, thus reducing the number of file I/O calls, and
** more importantly, reducing temporary file creation events. If these
** journals become too large for memory, they are spilled to disk. But
** in the common case, they are usually small and no file I/O needs to
** occur.
