GC statistics (was Re: big project ported)

[Matt Welsh]

I strongly recommend that people interested in improving GC performance in
GCJ look at the papers on the ExactVM from Sun Labs, two of which are at:
	http://www.sun.com/research/techrep/1998/index.html
Called "The GC Interface in the EVM" and "GC Points in a Threaded 
Environment". Perhaps the papers you really want to read are referenced 
from these.
	
It sounds like what many of you are talking about is generational and
exact garbage collection, something which the ExactVM (now called "EVM")
does very well. It should be possible to implement a very efficient 
GC system in GCJ -- but it's probably best to draw on the work that's been
done before in this area!
