Detailed Description
An OO equivalent of the internal FILEHANDLE variable and associated _sys_* functions.
FileHandle is an abstract class, needing at least sys_write and sys_read to be implmented for a simple interactive device.
No one ever directly tals to/instanciates a FileHandle - it gets created by FileSystem, and wrapped up by stdio.
Synchronization level: Set by subclass
