Comment (by kencu):

 Its true ... thread local storage is not available on 10.6 via clang.
 There might be a way to do it. gcc can offer TLS, but there could be
 standard library issues. Clang-3.9 *might* be able to build it against
 libgcc with fancy tricks and get you tls. See the cxx11 portgroup for
 thoughts on this.
