Detailed Description

Provides support for thread-safe output operations on character streams.

The stream operates on a per-actor basis and will print only complete lines or when explicitly forced to flush its buffer. The stream will convert any operation to a message received by a printer actor. This actor is a sequence point that ensures output appears never interleaved.
