67            mysqlnd makes a connection created through mysql_init()/mysqli_real_connect() always a 'persistent' one.
68            At this point 'persistent' is not to be confused with what a user calls a 'persistent' - in this case
69            'persistent' means that mysqlnd uses malloc() instead of emalloc(). nothing else. ext/mysqli will
70            not consider it as a 'persistent' connection in a user sense, ext/mysqli will not appy max_persistent etc.
71            Its only about malloc() vs. emalloc().
72
73            However, the bug is about malloc() and efree(). You can make make mysqlnd use malloc() by either using
74            pconnect or mysql_init() - so we should test pconnect as well..
