AFAIR there was an issue and they declined to implement it. They don't want to
maintain all kinds of features usually requested around HTTP as part of Angular
and I understand.
AFAIR I used streaming with the http package. I don't remember where. If I find
the code I can post it. It wasn't difficult, only a bit difficult to find.
