<div>It is not possible to free an individual term from a nif environment. If you want to have that kind of granularity, you have to create one environment per term that you want to individually collect. If the allocation cost of a new env is too large for
your application, you could pool env's and use enif_clear_env to re-cycle env's into the pool.</div>
