     54
     55Options for saving state:
     56
     57 1. incremental diff for sequential key-frames
     58 2. saving immutable openModels.list()
     59    a. saving to RAM
     60    b. saving to disk (pickle, sqlite, etc.)
     61    c. optimization issues (threading)
     62    d. see http://docs.python.org/library/persistence.html
