A more direct way to reproduce
from concurrent.futures import ProcessPoolExecutor, ThreadPoolExecutor
from time import sleep
def worker():
with ProcessPoolExecutor() as pool:
r = list(pool.map(sleep, [0.01] * 8))
def submit(pool):
pool.submit(submit, pool)
if __name__ == '__main__':
pool = ThreadPoolExecutor(2)
pool.submit(submit, pool)
i = 0
while True:
r = pool.submit(worker)
r = r.result()
print(i)
i += 1
