Tracealyzer groups the events into "instances" based on Instance Finish
            Events (IFEs), produced either by default rules or calls to the recorder
            functions vTraceInstanceFinishedNow and vTraceInstanceFinishedNext.

            If TRC_CFG_USE_IMPLICIT_IFE_RULES is one (1), the default IFE rules is
            used, resulting in a "typical" grouping of events into instances.
            If these rules don't give appropriate instances in your case, you can
            override the default rules using vTraceInstanceFinishedNow/Next for one
            or several tasks. The default IFE rules are then disabled for those tasks.

            If TRC_CFG_USE_IMPLICIT_IFE_RULES is zero (0), the implicit IFE rules are
            disabled globally. You must then call vTraceInstanceFinishedNow or
            vTraceInstanceFinishedNext to manually group the events into instances,
            otherwise the tasks will appear a single long instance.

            The default IFE rules count the following events as "instance finished":
             - Task delay, delay until
             - Task suspend
             - Blocking on "input" operations, i.e., when the task is waiting for the
               next a message/signal/event. But only if this event is blocking.
