Does it really hang here? If you apply the first patch, what is the
result (last couple of printed lines)?

OTOH, I've found a similar problem in the floats tree, which may occur
(with other symptoms) here. Does applying the second patch solve the
problem?

It looks like I often have to hit reload a couple of times.

Yup.

So I've committed it. Does not harm (still more efficient than
before), and examining it is on my todo list.
