If you want to recover the disk space then all you have to do is pack.

Yes, it will 'properly' get rid of them. That means notifying all contain=
ed=20
objects that they are about to be deleted so that, for example, they can=20
remove themselves from a ZCatalog. However it wont immediately reduce dis=
k=20
space - even a manage_deleteObjects can be undone..... until you pack.
