trouble .cache allready has such key

Hello, I was playing with your DeepnestPort and catch this weird exception. It happens in Background.cs when I run 2 different instances of NestingContext in 2 different thread(files are different). I would appreciate any clarification.

Thank you

Hi, it seems you're trying to use this code in your own specific way.
Can you explain what you want to get?
Please provide your code (whole project would be preferable) in order I can debug it and give you a hint
