As I see it, you could somehow work out a protocol for telling
something that is sending you 5000 TB of data to 'stop it
please', but (a) it could ignore you or (b) it could stop, but
then start again straight away, so it sends you 10MB, then
another 10MB, then another 10MB ad disk-blow-upeum.
This can happen with pretty much any protocol anywhere.
And that analysis is almost certainly one of the reasons why the
multipart/partial idea in MIME has never gone much of anywhere
as a useful tool.
