Isn't that a loose use of the term success originating in confusion
caused by abstraction?
We call it success because that's it's a word describing what we
expect it to do. The browser's actual xhr has no concept of success on
it's own, that is determined by the library/application based on
completion, http error codes, etc... The real success we are firing
that method in jQuery on to xhr is actually the concept of completion of
the xhr call, coupled with a non-fatal status code. The browser ends up
firing success because by calling abort we cancel all the remote
interaction and bring it to it's finished state, hence it is complete.
readyState == 4 is really DONE, not success, it's an indication that
the xhr has been opened and whether it succeeded, failed, or aborted the
request is over and is no longer doing anything.
I think calling error: with a statusText of abort would be the more
intuitive way of handling this.

It's not really clear what it should call - maybe it should only call
the complete request and neither the error or success. When I looked
into it recently some browsers called success and some called nothing
(Opera). I normalized it to success across the board but I'm open to
further debate.

Is it intended, that aborting an Ajax will call the complete calback
with the status success + the success-callback? In most cases noone
wants to handle an aborted request in his success-callback. I think,
you should introduce a new xhr-event/callback 'abort'.
