The client needs to know that some program is still using the slot
directory. stderrgfx.txt isn't a perfect solution to the problem but I
don't think there is any other mechanism to do it. I don't think the client
really knows about graphics apps other than being some extra files it needs
to download.

I suppose a better solution would be using memory mapped files to
communicate between science app and graphics app but that would be API
change.

In other words, I think it's better to keep stderrgfx.txt for now.
