What is the distinction between this and the above?  The above merges across all
VMs?

[Jacob, 2014/08/13 21:36:15]

removed this method and cleaned up the logic so currentCallFrames() continues to
just be the call frames for the specific VM.  merging then happens purely in
UnifiedScriptDebugServer. Required tweaking the API for ScriptDebugListener so
that the StackTrace isn't passed directly with the paused event..
