[Twisted-Python] UncatchableExceptions

<foom> exarkun: I suspect we should introduce a UncatchableExceptions constant somewhere <foom> exarkun: and require that all except:'s are preceded by except UncatchableExceptions: raise <exarkun> foom: It's possible that is a good idea. <exarkun> foom: I'm not really sure, though. <spiv> foom: With (KeyboardInterrupt, SystemExit, MemoryError, SystemError) ? <foom> spiv: yes I guess this would live in twisted.python somewhere, and the coding standard would be updated to require its use instead of bare "except:" Python-dev have discussed a similar measure for the python standard library (in the exceptions module), but hadn't come to any consensus last time I looked. Thoughts? Objections? -Andrew.
