Distinguish between "hard" and "soft" references to shared objects.  Sending
bitstreams use soft references and remove their mappings when only soft
references remain.
Working on tests for shared objects.
Revert complicated system of "soft" pointers, instead use hard references in
write mappings and listen for object destruction.
