   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.

      Forward progress guarantee is what allows for conversion between recursion and iteration for performance optimization. Otherwise these have different characteristics (recursion blows the stack, a loop hangs).
