   Insert screaming here.

   An infinite loop, with no library calls whatsoever, gets a system call inserted. That's a horrible surprise waiting to happen.

   The entire concept of the "forward progress guarantee" is broken. An infinite loop should compile to an infinite loop. Nothing more, nothing less.

      I think that a compiler option should control this. It can be a nice optimization, but the programmer should be able to opt out.

         The programmer can opt out by terminating the loop.
