/// ==================
///
/// This implementation hooks in through the XRay logging implementation
/// framework. The Basic Mode implementation will keep appending to a file as
/// soon as the thread-local buffers are full. It keeps minimal in-memory state
/// and does the minimum filtering required to keep log files smaller.
