FWIW, I don't think it helps /that/ much yet, but it seemed like a  
sane thing, and didn't break anything, so I decided to commit it anyway.

In theory, this should provide a bit more room once the area- 
generation begins. Blocks, inlines and lists will now release the  
references to their children once their last area has been added to  
the tree...

The larger documents I tested it on did also have large tables so  
maybe that explains why the effect was not immediately visible to me.  
For table-elements, something similar might be possible, but I  
couldn't get that to work just yet, hence why I decided to move it  
into checkEndOfLayout() for the moment, which is only used by the LMs  
I modified a few days ago to get page-number-citation-last working.
