Read/write concurrency can now be enabled in the SQL API by using
<code class="literal">PRAGMA multiversion=on</code> before accessing any
tables in the database. After multiversion has been enabled, it
can be temporarily disabled using the
<code class="literal">PRAGMA transaction_snapshots=on/off</code>.
