You can have code that runs everytime an exception is logged:

twisted.python.log.addObserver(f)

f(aDict) will be called for every logged message, including
exceptions/failures. Just make sure f() doesn't raise exceptions itself
or it will get removed.

If you have code that crashes the *reactor*, i.e. twisted quits, that's
a bug in twisted and you should add a report ot
http://twistedmatrix.com/bugs/.
