I was actually wondering if you could mix pseudo-region analysis with 
garbage collection.  The basic idea I had was, given a language with 
functions as first-class objects (like Java), have each function frame be 
it's own generation.  When the function exits, it tells the garbage 
collector to mark and sweep the whole frame- all objects either get 
promoted to a older generation or collected.

Or is this already being done?
