Kill jquery remote form submit

http://stackoverflow.com/questions/5085515/kill-jquery-ajax-form-submit#
I am remotely submitting a form potentially several times in close
succession. For this particular case, debouncing is not an option. I am
looking for the jQuery equivalent of |.abort()| for remote forms
submitted using |.submit()| so I can cancel all previous submissions
when a new one is made.

Assuming there is a solution, I am wondering if this will reduce the
server load, or if I would need to somehow cancel the request
server-side as well.

Thanks in advance, Garrett
