Bug description:Multiple Queries on a single conenction

Description:
------------
Hi, trying to build a generic DB object handler for mySqli, and have hit an
issue where we can't have more than one open query on the same connection.
Is this a bug or 'expected behaviour'?

Looking at the mysqli.c source code, it looks like it should have been
possible, but it looks like the second object overwrites the first...



I have put a sample snippet below of what I am trying to achieve.... if
this helps.



Any help greatly appreciated....

Expected result:
----------------
Array

Array

    [foo3] => 0000-00-00 00:00:00

Actual result:
--------------
Array

(

    [foo1] =>

Array

(

    [foo2] => 2009-09-15 12:05:02

    [foo3] => 0000-00-00 00:00:00
