[Pharo-users] Image Cleaner no longer useful?

Hi, and sorry if this has already been discussed.
In Pharo 3, I used to be able to do:
ImageCleaner cleanUpForProduction
and that would correctly remove a lot of unneeded code in the image when 
preparing for a productive release.Then I would save the cleaned image, and 
since it had been cleaned, it would be smaller than the original development 
image (say from 60 mb to 25 mb).This process would take about 2-3 minutes.
Then, in Pharo 4 it seems some changes were made here, since the same process 
took a lot more, like 20 minutes.
When I first tried Pharo 5, I was happy to see that it was again down to 2-3 
minutes.
And here comes my question...Why is it that since some 2 months ago (maybe 
more), the Pharo 5 images once again require like 20 minutes to complete the 
cleanUpForProduction process?
Also, and this is the most relevant to me, it no longer reduces the image 
size.So if I want to release a Pharo 5 version based on the latest images, I 
would be shipping a product that is more than twice the size of previous public 
versions of my software!
Thanks for any insights into this. If it is a known bug, I would like to know 
if there is any workaround, or alternative objects that I should be using for 
the process.Also, if it would help for me to run any tests in particular to 
share and help in fixing this, please let me know.
