Try the following.

Make each shared object keep track of how much it is used. In CLONE, increment the usage of each object that the thread will actually use. In DESTROY, decrement the usage of each object that the thread incremented. The key is that you have to decrement all of the things that you increment.

This should work much, much better than having each thread increment everything, then only decrement itself. Which is what your code currently does.

That said, I would personally advocate avoiding using threads unless you absolutely need to. Threads are always a huge complication, and I'm a big advocate of trying the simplest thing that could possibly work.
