Hello...
I have noticed that after installing packages (say for example starting with a dev image and loading everything else you need), my image will swell considerably (as noticed both on the disk after saving, and with MemoryUsage). Garbage collection and saving doesn't seem to fix it, but if I re-run the level playing field script, it seems to clean things up.
I'm not sure what it's doing, but I thought it worth passing on...
However, if you do this a lot (because you mess things up so badly that you have to unload and re-load packages to get things straightened out, which I can confess to on the Beginners List), make sure you do a Smalltalk condenseChanges every now and then, or it will come back to bite you too!

It's probably because of this line in http://installer.pbwiki.com/LevelPlayingField-Monticello15 :
SmalltalkImage current fixObsoleteReferences
Try running that and see if it helps.
Sorry for bringing this up again, but nothing works so well for getting an image back down to size after installing additional packages (especially big ones, like Aida or Magma) like running LPF. The fixObsoleteReferences does nothing...any other ideas? Whatever it is is present in the pharo script as well, and does something in a way that doing a garbage collect after the end of the script immediately shrinks the image--in this case from 50Mb to 25Mb! Take care,
Rob

LPF is running SmalltalkImage current cleanUpAll.
We recently started a convention that all classes that can free up some memory prior to saving an image implement #freeSomeSpace, or #cleanUp.
One of the biggest offenders is Monticello, it caches quite a lot of stuff when loading packages. There is a menu item for cleaning Monticello caches manually.

Thank you for the explanation! Take care,
