                                have been
  Most of the shootout examples could be run on a 16 bit DOS system.  If
"16 bit DOS programs" was a requirement even fewer people would pay any
attention to the shootout site(s).  Hyperthreading and now multicore CPUs
are clearly coming, and a language that makes it easy to get benefits from
them is to be preferred to a language that doesn't do that.
