I'd argue against general thread cancellation. Inter-thread

in a signal handler, which is effectively thread cancellation.
Can you give an example of such "cancellation"?
In any case, this would be a side-effect of the current implementation, not
officially supported behaviour.
It's not only documented behavior, it's an example in the official
documentation. See
http://docs.python.org/library/signal.html#example
where an exception is raised in a signal handler.
