Question about pandas

mytest.py:

import time
import pandas as pd
time.sleep(1000)
print(1)

Excute it and check threads with:

ps -eaf -T | grep mytest

And 24 lines show up.

But if I remove import pandas, only one line remains.

I can get the same result with htop. So why does pandas really create threads during import?
