Re: parallelism

Of course, I was too fixed on GTK to ignore GNUstep.

This could be automated, so no vigilance needed, but I keep having in
mind that different languages are likewise more/less suited for that.
(change the preprocessor)
So I'm not sure, you're talking Obj-C or Java Swarm?  Anyway, could it be 
helped by proposing the use of @private ?

I still don't get this fully, you mean scheduling on the algorithmic
level, or is there an example for fine-grained scheduling?
Isn't this called iterators?

I'm not sure what you mean by this, is there any literature on that?

Had this already on my todo list.  Next is releasing an eArticle,
and reading a book on Java-Linux to get into it again.  Just one
question: weren't there some patent problems with that hypersphere
visualization Java tool?  Don't want to get into such waters. VRML?
