Comment (by simonpj):

 Can you explain a bit more what the problem is?  In the description what
 is `things1`?  In general if a Haskell process deserialises, say from a
 network message, the key of a static pointer, there is no guarantee that
 it'll be in its SPT.

 Also I don't understand the API.  What's unsafe about looking up a static
 pointer?  Surely we shouldn't be exposing low-level details like
 fingerprints?
