But so is the single buffer and the single position.  e.g. if one were to call your unified primitive below to fill the buffer that wouldn't prevent another thread reading at a different position into the same buffer and trashing the contents from the POV of the first thread. Since the programming tools are essentially single-threaded it's not *that* bad a problem, unless you're debugging source access (I *think*).

Gotta start somewhere. Bottom is often good. Then other people can build upon that.
