Apparently HTTP doesn't define timeouts so I think it'd be bad for us to 
add any requirements. So yeah, I think creating your own timers or 
relying other mechanisms to abort requests is the way to go.

I believe that in mozilla we will enable the stop button when the 
request is made and pressing that will abort the load.

I'm not sure we want to dictate to browsers what to do here. I would not 
be surprised if some browsers disabled all scripts once you leave a page.
