v0.3.3

Version 0.3.3 has the following fixes/feature improvements:

• stderr/stdout/stdin are mostly proper Readable/Writable streams, and implement the appropriate EventEmitter interface.

Some notes about our implementation:

• Duplex streams (which stderr/stdout/stdin all are, as we are emulating these OS resources) emit the _read event when its buffer is empty and someone is trying to read from it.

In the future, we might decide to bind more closely to Node's implementation of streams, including its extendable abstract implementations.
