FYI: Measurement on my environment:
http://www.atdot.net/sp/raw/e4uylm

Observation:
- Works!! :)
- SOme of benchmarks are slow down because of
  - not enough WBs to reduce GC (marking time)
  - but increase WB overheads (for Array access)
- vm3_gc speed up! , but it is mystery because
  there are no old objects and
  GC.start run full-GC.
  It seems that full-GC (== current M&S) is faster
  with my some my modification (removing mark_counter, etc).
- Computing intensive simple benchmarks are not affected.
