Combine that with data event/change logging and you have effectively the
same thing as what many apps think they need to use a database library
for.  Replay the entire log of data changes internally on infrequent app
startup to generate your internal state.  when the log file is getting to
big, write a full state snapshot and continue logging changes from it.
no need to save the entire pickle everytime something changes.
