Can you compile a prioritized list (or screenshot) of memory-hungry  
functions?

When you say node_page_default() allocates a lot of memory; is that  
inclusive or exclusive the methods called from within  
node_page_default()?  I'm asking because node_page_default() doesn't  
seem to do any caching.
