[PD] Delete scalars

It's not the list management that's the problem, it's having a way to track down 
all stale pointers and un-point them.  Currently this is managed by maintaining a
per-list "stub" that the pointers all check through.  one could have such a stub
for every scalar, but this would add a lot of overhead.  Alternatively, all
"gpointers" to a given scalar could register themselves somehow, and every time
one deleted a scalar one would track down every pointer to it through the
registration mechanism.  I've been unable to convince myself that the machinery
could be kept lightweight and efficient.
