Sure, I've already done that. I compared one version using "__thread" 
and one version without "__thread". I do see the differences of the 
disassembly but that doesn't help me, I don't know assembly. The only 
interesting I could find is that it does perform a "call", the version 
with "__thread".

I don't have access to a machine running Lion+ but you could take a look 
at this:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52268

That's a bugzilla issue for the same thing for GCC. The comments contain 
some disassembly of uses of "__thread".
