  False example. exit(2) practically constitutes an unhandled
exception and tla doesn't even bother to clean up after itself.
  
  Sure you can write useful tools without exceptions, only that it is
harder.  Not a surprise that virtually EACH language and API provide
some means for "out-of-band" code paths (however crippled they may
be).  For example setjmp/longjmp, pthreads cleanup handlers,
unwind-protect, atexit (of the non-traditional forms of exception
handling).
