  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=58509

  Log:
    new benchmark for SizedQueue
    
    The performance of SizedQueue is a bit more complex than
    regular Queue, so it deserves a separate benchmark.

  Added files:
    trunk/benchmark/bm_vm_thread_sized_queue.rb
Index: benchmark/bm_vm_thread_sized_queue.rb
