I guess it depends on what you are trying to do.
The IExecutionDMContext contained in the ISuspendedDMEvent indicates
which thread or process just got suspended.  If you don't have a
thread or process in your case, then maybe using an ISuspendedDMEvent
is not the best way to go.  

You can have a look at StackFramesVMNode.buildDelta() or
StackFramesVMNode.getDeltaFlags() to see how the stack frames
are refreshed based on different events that are received.

You can see if any event fits the behavior you are trying to
achieve.  If not, you may choose to definea new event altogether
to notify the views that something happened that requires an
update.
