I really notice a difference.

You should have seen only one such message for every ant run on the ATL 
console. After the Ant run, you should see the message "Removed AM3 ant log 
handler".

Can you verify that your ant script is only executed once and whether you get 
the "Removed AM3 ant log handler" message or not?

I do. I have also verified that dispose() is called on all models after an Ant 
run.
