[news.eclipse.tools.emf] Re: newbiew qn: how to add a viewer to the EMF

Charles,

I didn't know javalobby had such a thing.  It's  more than enough to 
manage this newsgroup's traffic for me.  

Somehow I think holding a write lock for minutes will not be a good 
thing.  The UI would not be able to even read the model for this whole 
period of time so had better not even try.  That's why my sense is that 
something that takes five minutes should produce no visible changes 
until it's done.  Let the UI view an old plot until there is a new one 
and then switch it when its done.
