NodeJS Streams

Current implementation is known as streams2.
Introduced in node v0.10.
"suck" streams instead of "spew" streams.
Instead of data events spewing, call read() to pull data from source.
When there isn't any data to consume, then read() will return undefined.
Adding a data event listener will switch the Readable stream into "old mode", where data is emitted as soon as it is available rather than waiting for you to call read() to consume it. This requires you to handle backpressure problems manually.
The pipe method helps write less code and handles back-pressure.
If you add an end listener and don't ever read() or pipe(), it'll never emit end.
