thread safe

hi, do I need to lock "item" or its thread safe?

At the moment, I'm still trying to track down a seemingly random occurrence of a panic. The way it's being used in the current project I'm working on is with swapping unsafe pointers. If you'd like to test it out and see if it's threadsafe for me, I'll happily give you credit and include you in the README.
