-/*
- * A trace is an optional thread serial number plus N frames.
- *
- * The thread serial number is added to the key only if the user asks for
- * threads in traces, which will cause many more traces to be created.
- * Without it all threads share the traces.
- *
- * This is a variable length Key, depending on the number of frames.
- * The frames are FrameIndex values into the frame table.
- *
- * It is important that the thread serial number is used and not the
- * TlsIndex, threads come and go, and TlsIndex values are re-used
- * but the thread serial number is unique per thread.
- *
- * The cpu=times and cpu=samples dumps rely heavily on traces, the trace
- * dump preceeds the cpu information and uses the trace information.
- * Depending on the cpu= request, different sorts are applied to the
- * traces that are dumped.
