That'd be easy to add, and would make implementing named locks easiest.

We'd make a special flag to set/add/replace that adds the item to the
connection's "to delete" list off.  Conn dies, we go delete all the items
it touched in that mode.

Then the lock acquirer could just poll.  (which is ghetto, but we're
talking about the easiest way to implement this)
