    Thanks, that's good to know going forward. It turns out that stripping the

<!DOCTYPE refentry [
<!ENTITY % mathml PUBLIC "-//W3C//DTD MathML 2.0//EN"
                  "http://www.w3.org/TR/MathML2/dtd/mathml2.dtd";>
%mathml;
]>

prolog from my documents will prevent jing from hanging. Unfortunately it will also
prevent some of them from validating, since they use MathML entities like &lfloor; .
I filed a bug on the jing project page to ask about this but perhaps I'm missing
some other way to be able to use these entities that would work around this issue?
