Are there any side-effects of re-executing a SQL statement like INSERT,
UPDATE or DELETE after sqlite3_exec returns SQLITE_LOCKED (like some
triggers executed twice, etc)?
No. SQLite is atomic: It executes SQL statements to completion or not at
all.
In your case, SQLITE_LOCKED indicates that sqlite3_step() did not
succeed and no changes have been written. So in order to achieve your
goal you have no other choice but to re-execute the statement when the
database is no longer locked.
