// FDR (Flight Data Recorder) Mode
// ===============================
// The XRay whitepaper describes a mode of operation for function call trace
// logging that involves writing small records into an in-memory circular
// buffer, that then gets logged to disk on demand. To do this efficiently and
// capture as much data as we can, we use smaller records compared to the
// default mode of always writing fixed-size records.
