The oft-overlooked problem with threaded code is that you can't
guarantee you can cancel something else in another thread.

So sure, if the bufferevent isn't in-flight in another thread, you can
cancel it. But you have to be prepared for the cancellation to fail
because it's already involved in an IO.

Just putting it out there,
