There's been an attempt to get rid of the Monitor field, which takes up
one word, but it didn't seem to have gone anywhere the last time it was
discussed.  I believe originally it was always initialized, but lately
it seems to have been changed to be lazily initialized, so at least
you'll only incur the computational cost if you actually use it.
Nevertheless, the field itself is still there.
