* concurrency. PHPs internal files session handler also implements locking.
*
* Attention: Since SQLite does not support row level locks but locks the whole database,
* it means only one session can be accessed at a time. Even different sessions would wait
* for another to finish. So saving session in SQLite should only be considered for
* development or prototypes.
*
* Session data is a binary string that can contain non-printable characters like the null byte.
* For this reason it must be saved in a binary column in the database like BLOB in MySQL.
* Saving it in a character column could corrupt the data. You can use createTable()
* to initialize a correctly defined table.
