 Can we enable online migration as a kind of GC?  We're a long way there.

 Enablers:
  * Migrate already updates moved instances to point to new store
 controller
  * New objects will be created in the new store controller by default,
    if *store-controller* is updated in each thread

 Needed:
  * We need to make sure that references to btrees, slots, etc check for
    access against a 'migrating' store so they don't complete until the
 object
    in question has itself been migrated.
  * Does access to an 'old' instance migrate it, poll-wait, etc?

 Perhaps a full online GC solution will pre-empt this.
