Thanks for clarifying the use case. I think it's a good idea with multiple thread pools and below outputs for the program with the PR is more easier to debug than the current code.
# ../backups/bpo34720.py
from multiprocessing.pool import ThreadPool
def f(x):
from threading import current_thread
print(current_thread().name)
return x*x
if __name__ == '__main__':
p1 = ThreadPool(5, name="process-1")
p1.map_async(f, [1, 2, 3])
p1.close()
p2 = ThreadPool(5, name="process-2")
p2.map_async(f, [1, 2, 3])
p2.close()
p1.join()
p2.join()
# With patch
$ ./python.exe ../backups/bpo34720.py
process-1-Worker-0
process-1-Worker-1
process-1-Worker-0
process-2-Worker-0
process-2-Worker-1
process-2-Worker-0
# Without patch and removing name parameter
$ python3.7 ../backups/bpo34720.py
