That would be it. There is no locking of the various databases between
processes. I suppose we could implement something, but the vagaries of
network file systems and cross-platform demands have always made that task
problematic. Maybe we should expand your safe_pickle code into
safe_pickle_read and safe_pickle_write with a corresponding bit of file
locking code they can invoke (which will probably be ugly as sin - but
hidden away in a dark corner - once it's complete).
