Ok, so this is unreliabledc.send(myBigBlob);
where myBigBlob is probably bigger than the buffer on my IoT device?

That is knowable. This end knows how much buffer the far end said it still had free.
Throwing an error is reasonable. If the channel is reliable closing the channel is 
the right thing to do. If it its partial unordered , then the channel should survive.

Sounds like chrome does the correct thing, but the doc only covers the reliable case.
