Yes, I've seen your commits.

I'm not sure but, can't the parent send sighups to all threads? (this
is what is commonly done in processes spawned by servers, but I don't
know if this is possible with threads)

However, this has the problem that the interrupt is not inmediate, right?

I wouldn't implement this, too much overhead.

I think the simplest would be #1. After all, a Ctrl+C is equivalent to
a SIGKILL sent from the console, right?
