Actually, we could even get rid of the ChunkedData interface and do
something like
interface Stream {
AbortableProgressFuture<ArrayBuffer> readBinary(optional unsigned
long long size);
AbortableProgressFuture<String> readText(optional unsigned long long
size, optional DOMString encoding);
AbortableProgressFuture<Blob> readBlob(optional unsigned long long size);
AbortableProgressFuture<void> readBinaryChunked(optional unsigned
long long size);
AbortableProgressFuture<void> readTextChunked(optional unsigned long
long size);
};
where the ProgressFutures returned from
readBinaryChunked/readBinaryChunked delivers the data in the progress
notifications only, and no data is delivered when the future is
actually resolved. Though this might be abusing Futures a bit?
