Besides the obvious ones (storage for events & states, memory usage also
depends on what features you use: event posting, history, etc.). It is
theoretically possible to determine the exact memory requirements in advance
but it's probably much easier to simply let the machine run through all
possible states (e.g. with the unit tests you've written) and observe the
amount of memory used. If that is not an option for you please let me know.
