If you comment out agg you are using a gui backend presumably (which
one) and most of these are known to have some leaks, some of which are
beyond our control. Michael has recently made some change to
significantly reduce a gtk leak.
When you say you are working interactively, do you mean from the
python or ipython shell? ipython holds a reference to the names the
main module namespace, which could be preventing a gc cleanup. After
reading your post, I am not clear if you still have a problem or not.
