XHR abort(): IE hangs after two aborts.

[Sri]

Hi,
We have a strange problem with XHR (IE6.0).
If we abort a request after it times out, we notice in HTTP
tracker(Fiddler), that one of the channels dies (i.e not usable
anymore), and hence after two aborts, we are left with no more AJAX
connections, and the only solution is to close the browser.
Has anyone encountered such a problem before?
I understand that IE allows only 2 parallel AJAX requests at a time,
but am not sure aborting one of them actually frees up the resources as
it is supposed to.
Moreover, if the window is closed before the request comes back, the
same thing happens. I had to shut down all instances of IE to solve
it!!
That makes me wonder if the abort() functions correctly ?!!

Thanks,
Sri
