So does Jan, and to be honest, his tester is better than your graphs,
because it knows the difference between ggc and non-ggc memory, etc.
Looking at Jan's tester shows that Diego's patch to make the new pt
solver the default wiped out some of my improvements from the decl
hierarchy
See

vs

A lot of this is probably because the constraint graph is currently ggc
alloced.
I'll fix that in a moment.
