Okay, so we've got exceptions to transparency for transactions and for
"weak references." Now what about programs that build up data structures
in memory that are more efficient to re-create than to store? They must
be careful to explicitly dump pointers to them when they get a message
to shut down (assuming they get such a message). That seems like another
exception to transparency.
