* Notes:
* (a) write_<type>() and add_<type>_annotation() should be called in the order that fields
* and annotations are defined in the atom.
* (b) set_timestamp_ns() and set_atom_id() can be called anytime before stats_event_write().
* (b) set_atom_id() can be called anytime before stats_event_write().
* (c) add_<type>_annotation() calls apply to the previous field.
* (d) If errors occur, stats_event_write() will write a bitmask of the errors to the socket.
* (e) Strings should be encoded using UTF8 and written using stats_event_write_string8().
