+ * A helper function is provided here to convert from time to process

+ * Note: The last point is exactly why it would not be so easy to add the
+ * vertical line functionnality as in the original version of LTT. In order
+ * to do so, we should keep all processes in the list for the duration of
+ * all the trace instead of dynamically adding and removing them when we
