Stefan,

it would not be impossible to implement this - except I see there is no way
around the risk of deadlock if up is streamed or the DoS issue if up is
held in memory.

So rather than encourage a false belief that such a mechanism might work
for arbitrary content, I think it is better for servers to ignore all
upgrades with any content.

cheers
