GC benchmarks

The old SPECjbb2000 benchmark was pretty much a pure test of GC 
peformance (with a little bit of pure CPU overhead thrown in).  The 
(current) SPECjbb2005 benchmark was modified to throw in more system 
complexity (though I don't recall the details) and is less of a GC 


Unfortunately, the results aren't real current, and aren't organized in 
a way to allow you to compare GC algorithms very readily.
