-Subject: [PATCH 10/10] Allow read-only memory mapping.
-
-In memory-mapped I/O mode, SQLite writes pages by using memcpy() from
-the staging memory into the underlying memory-mapped file.  This allows
-anyone in the process to also write into that space.  Modify SQLite to
-map things read-only.
-
-TODO: Upstream.
