Local process worker protocol. This worker runs as a local process and
communicates via stdin/out.
@ivar _ampProtocol: The L{AMP} protocol instance used to communicate with
the worker.
@ivar _logDirectory: The directory where logs will reside.
@ivar _logFile: The name of the main log file for tests output.
