Sometimes ads load into incorrect spots, or double up.

What steps will reproduce the problem?
1. Set up lazyload ads in the usual way, but test using different size ad zones 
on the same page, all having a div with the same class referred to in the 
lazyload call.
2. Pull ads from a slow ad server.  In my case, the ad server is OpenX and its 
running on the same hardware but a different domain.

What is the expected output? What do you see instead?
Expected output is that ads display in all their expected spots.  What I see 
instead, _occasionally_, is an ad showing up in the wrong location or two ads 
trying to load into one location.

What version of the product are you using? On what operating system?
1.4.2 - Linux 2.6.18

Please provide any additional information below.
Apache 2.2.21 / PHP 5.2.17

I realize this problem report is murky, but others have been experiencing this 
issue as well.  For some reason, if the ad pulling is slow, lazyload can't 
always keep track of where to place the ads.
