Comment 2 for bug 1795813

Via code inspection, it looks like this affects cosmic as well:

/**
 * Release a mysql connection
 */
static void conn_release(private_mysql_database_t *this, conn_t *conn)
{
    this->mutex->lock(this->mutex);
    conn->in_use = FALSE;
    this->mutex->unlock(this->mutex);
}
