How to reproduce the behaviour

nlp = spacy.load('en_core_web_sm')
array_text = ['Hi there, this is a test' for i in range(0,10000)]
processed = nlp(', '.join(array_text))

This will cause 16 threads on my macbook pro to spin up for Spacy. So is Spacy running in multi-thread mode by default? How do I disable this behaviour? I was under the impression that it would only run in multi-thread mode if I used the nlp.pipe.
