At the moment I do have such array at the side (symetric to
tree_bb_roots) for PHIs, so it does not solve your problem inside PRE.
(the EPHIS are stored separatly from PHIs lists, right?)
In fact PRE is only place where I still need pushcontext/popcontext on
tree path as it saves some stuff in stack.
I hope you will take a look on it yourself, once I am done with the
rest.
