I think a useful feature that would perhaps be able to handle this
type of problem is a 'halt'/'continue' routine for message processing.
 Say, for example, it could be automatically handled during a stack
overflow-clear the stack and send an error message.  Or triggered by
the watchdog to catch bang/until problems.  Something like that would
give you the opportunity to save/re-load or add additional objects to
stop the infinite loop, when not intended.
but it would still run into those problems of finding an arbitrary
condition to trigger the 'halt'
