[dart-misc] Pause / Result a stream in await for clause

[Adam Lofts]

Hi,

I have a bit of code like this:

await for (var v in linesOfDataFromHttpClient()) {
slowFunction(v);
}

1. If linesOfDataFromHttpClient() is big then does this buffer a lot of
data in ram?
2. Can I fix this by calling pause on the stream?
3. Do I have do re-factor the await for in order to get the
StreamSubscription to call pause/resume?

Thanks in advance for any insight,
Adam
