The whole point of thread local data is that it's only accessible from a 
single thread. If you want to share it with another thread you have, as 
far as I know, there options:

1. Declare it as "shared"
2. Declare it as "immutable"
3. Make a copy, i.e. serialize the data

Looking at your original example I don't understand why the immutable aa 
won't work. That's the whole point of immutable, it's safe to share 
among threads. It's probably a bug somewhere. I think someone else can 
answer these questions better than me.
