Comment:

 Well, today has been a day for digging through PHP source.

 Nacin is correct, `new_link = false` is different to `mysql_pconnect()`,
 and mysqli's `p:` notation is the equivalent of `mysql_pconnect()`.

 `new_link = false` is for forcing subsequent calls of `mysql_connect()`,
 in the same process, to use an established link that matches the connect
 parameters of that call. mysqli doesn't have an equivalent to this.

 With that in mind, attachment:wp-db.php.4.patch is unfortunately the
 incorrect solution for this problem - instead, `MYSQL_NEW_LINK` is
 deprecated for use with mysqli, as of 3.9.
