  New Revision: 43547

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=43547

  Log:
    * benchmark/bm_vm1_gc_short_lived.rb: added.
      These GC benchmarks do not reflect practical applications.
      They are only for tuning.
    * benchmark/bm_vm1_gc_short_with_complex_long.rb: added.
    * benchmark/bm_vm1_gc_short_with_long.rb: added.
    * benchmark/bm_vm1_gc_short_with_symbol.rb: added.
    * benchmark/bm_vm1_gc_wb_ary.rb: added.
    * benchmark/bm_vm1_gc_wb_obj.rb: added.
    * benchmark/bm_vm_thread_queue.rb: added.
      Thie benchmark is added to know how fast C verion of thread.so.
