+Adapted from Debian: 
https://sources.debian.org/patches/sqlite3/3.32.3-1/20-hurd-locking-style.patch
+Upstream status: Not upstreamed.
+
+This patch is needed to get offloading to work.
+
+Sqlite can use simple file locking mode, but that does not work for the Hurd;
+a second sqlite process fails with a "locking protocol" error.
+
+See also: https://bugs.debian.org/529734.
