+ * FUTURE CHANGES:
+ *
+ * The timestamp functionality has intentionally been
+ * split in two parts for future use even though it
+ * is not used like this today. take_timestamp() takes
+ * the timestamp and calculate heap need for it (which
+ * is not constant). write_timestamp() writes the
+ * timestamp to the allocated heap. That is, one typically
+ * want to take the timestamp before allocating the heap
+ * and then write it to the heap.
+ *
+ * The trace output functionality now use patch_ts_size(),
+ * write_ts(), and patch_ts(). write_ts() both takes the
+ * timestamp and writes it. Since we don't know the
+ * heap need when allocating the heap area we need to
+ * over allocate (maximum size from patch_ts_size()) and
+ * then potentially (often) shrink the heap area after the
+ * timestamp has been written. The only reason it is
+ * currently done this way is because we do not want to
+ * make major changes of the trace behavior in a patch.
+ * This is planned to be changed in next major release.
