SqliteRevMap: wait indefinitely for database lock Python sqlite has 5 seconds timeout by default, which means if a writer holds the lock, and the second writer will error out after 5 seconds. In our use-case, it makes sense to just wait. However, sqlite does not support waiting forever (see sqlite3_busy_timeout). Therefore use a while loop to workaround.
