pause() in data callback about node-byline HOT 2 CLOSED

Here's what it says in the node.js docs:

stream.pause()

Issues an advisory signal to the underlying communication layer,
requesting that no further data be sent until resume() is called.

Note that, due to the advisory nature, certain streams will not be
paused immediately, and so 'data' events may be emitted for some
indeterminate period of time even after pause() is called. You may
wish to buffer such 'data' events.

It's worth mentioning that streams2 in node v0.10 provides deterministic pause behaviour and is now fully supported by byline.
