IMO this is API design that should be done without the time pressure
of a beta. I'd like you to experiment a bit with the
setdefaulttimeout() approach to see if it is workable though.

itertools is new and yours; if you're comfortable with this, I'm okay
with it.

Interesting. My own need is not for patching but for a three-way
merge. If you could add a direct API for that, it'd be great.
difflib.merge(mine, old, yours) -> new. With conflict markers a la
diff3 -m -E.

I'm +0 on that.
