    /*
        mysqlnd makes a connection created through mysql_init()/mysqli_real_connect() always a 'persistent' one.
        At this point 'persistent' is not to be confused with what a user calls a 'persistent' - in this case
        'persistent' means that mysqlnd uses malloc() instead of emalloc(). nothing else. ext/mysqli will
        not consider it as a 'persistent' connection in a user sense, ext/mysqli will not apply max_persistent etc.
        It's only about malloc() vs. emalloc().

        However, the bug is about malloc() and efree(). You can make mysqlnd use malloc() by either using
        pconnect or mysql_init() - so we should test pconnect as well.
