fizzix is on a distinguished road
The current algorithm for pass-wall monsters around perma-wall is a bit hacked together, but it mostly works, and it was enough of an improvement over the old version that I lobbied for it to go in.

When a passwall monster is adjacent to a perma-wall it uses the normal pathfinding routines, so Morgoth won't be able to figure out how to tunnel through a small opening in permanent walls. However, he will be able to navigate permanent wall areas which is a huge plus.
