Naw, I just disagree.  Saying that the creator is responsible for 
cleanup is like saying that because some objects need an explicit 
"close," we should force those semantics onto all objects.

If you have a thread local that requires special semantics, go ahead and 
provide the special code for those objects.  The rest of the code can 
use a common cleanup up mechanism that MOST objects require: just GC them.
