Poison deleted ptr-list entries.
Our current PREPARE_PTR_LIST/RESET_PTR_LIST implementation
has a bug: if we ever hit a block of pointers where every
single pointer has been deleted, it doesn't understand to
skip over it, and instead uses the first (deleted) entry.
This at least causes a nice SIGSEGV rather than random
behaviour. I'll have to think about how to do the PTR list
traversal fix nicely.
