Re: [cdt-dev] multi debug context stepping in DSF 
I don't know how to update a specific debug view button in DSF. 
If there is such way, please let me know. 

>>> Should the Suspended or Resumed event cause the views to refresh?  
I think platform doesn't know anything about DSF Suspend and Resume events therefore can't handle them. 

Here is my stack trace when DsfResumeCommand.canExecute() gets called. 

Thread [main] (Suspended (breakpoint at line 45 in org.eclipse.cdt.dsf.debug.ui.actions.DsfResumeCommand))	
	org.eclipse.cdt.dsf.debug.ui.actions.DsfResumeCommand.canExecute(org.eclipse.debug.core.commands.IEnabledStateRequest) line: 45

going throw the call graph of IDebugCommandHandler.canExecute() I didn't see anything useful I can hang on to.

I'm not entirely sure how the view refreshing logic works.
Should the Suspended or Resumed event cause the views
to refresh?  Or do we really need a new selection to happen?
