I'm suggesting that one shouldn't (no matter whether it can be done or not,
"conformance" aside for a moment).

Well, let me put it this way: feel free to fool yourself into believing that 
it's somehow going to make your application safer/robuster ("better"), using 
the following {anti-}"pattern":

extern "C" void* thread_routine_wrapper( void* arg )
{
  try {
    return call_something( arg );
  }
  catch( const pthread_cancel_e& ) { throw; }
  catch( const pthread_exit_e&   ) { throw; }
  catch( ... ) {} // ignore 
  return "HI_THERE_COMMA_TAKE_THIS_UNCAUGHT_EXCEPTION";
}
