Now that I look at it, that does seem odd, that the delete worked at all 
for me.  hmmm ...

I've always kinda wondered about reusing XMLHttpRequest objects; whether 
it's really kosher to do so or not.  It doesn't seem like it should be, 
but of course, you can, given the API, so people will do it.

Maybe try creating a new one each time, deleting it after finishing 
processing it.  The logic on how to clean up the multi-used XHR objects 
may be a bit messy - just doing a single request with each, and then 
cleanup afterwards, may give you better results.
