Although since Python 2.0 +the sys.excepthook variable has been available, for ease and potential +backwards compatibility (or to be more realistic +backwards-PARTIAL-compatibility!), the code catches errors by +assigning a custom object to sys.stderr and monitoring calls to it's +writ) method. Such calls which take place with a new value of +sys.last_traceback stand as evidence that at interpreter error has +just occurred; please note that this means that NO OTHER OUTPUT TO +sys.stderr WILL BE DISPLAYED. THIS INCLUDES "warnings" generated by +the interpreter. As far as I am aware, unless your code itself writes +to sys.stderr itself, these will be the only things you miss out +on--and many, if not most or all, of these will occur before your code +even gets the opportunity to set one of these file-like objects in +place.
