Re: [rvm-research] Add more statistics data related to Garbage Collection

The instrumentation that produced the stats for the DaCapo benchmarks 
paper here:

http://cs.anu.edu.au/people/Steve.Blackburn/dacapobench.org/dacapo-graphs/index.html

is available in the DaCapo benchmarks source repository, here:

http://sourceforge.net/p/dacapobench/dacapobench/ci/trunk/tree/tools/measurement/

The patches are very out of date (they're for Jikes RVM v2.4.6), but if 
you bring them up to date they might well do what you want.

cheers
