Anyone who builds needs to pull BuildSystem and reconfigure, and then a bunch

I made this change because synchronized printing was cutting off my
stuff. Now the queue is dynamically allocated so it can accomodate
any size string.
I tried ex7 and it runs fine for me, even under valgrind.
Shi, can you reproduce this with a Sieve example?

not saying to change back the code, just to be careful and check it.

Pushed a fix. I missed the Viewer when I

I am not against requiring SetFromOptions() to create default objects. We
already require it to set a default type.
