Mark, Yes, after looking at the code it does make sense. The reason is that Matt made me "improve" the -xxx_converged_reason to use viewers; but in your case there will be multiple threads (each associated with different KSP objects) each monkeying with the same (default) viewer thus possibly corrupting it.
I'll have to think a little bit about the best way to keep the functionality but be thread safe.
