Instantiating multiple thread pools throughout a code base causes issues when attempting to perform operations on said thread pools.

Thanks for the bug report! I wrote a short test program that allocates two thread pools and pushes different tasks to each pool, and did not encounter any issues. Please provide a minimal working example that reproduces the bug.
