Simplifying the reproducing example a bit more:
from concurrent.futures import ProcessPoolExecutor, ThreadPoolExecutor
from time import sleep
def submit(pool):
pool.submit(submit, pool)
if __name__ == '__main__':
pool = ThreadPoolExecutor(1)
pool.submit(submit, pool)
while True:
with ProcessPoolExecutor() as workers:
print('WORK')
workers.submit(sleep, 0.01).result()
print('DONE')
print('OK')
