Hi @millerdev and @llazzaro,

I run into this error when starting multiprocess worker pool on Windows,
Error details:
Exception in thread Thread-2:

Machine is Windows 10, python version is 3.6.
Redis is running on it's default port.
The script for starting pool is identical to code mentioned documentation.
The script is running on Mac perfectly.

I would appreciate any ideas.

Thank you.
