Comment (by kencu):

 it's a bit complicated, Pete. See this <https://en.wikipedia.org/wiki
 /Thread-local_storage> for an overview. On 10.6 (and for that matter on
 10.4 - 10.8, I think) the only way to get it is to use the new versions of
 libstdc++ provided by gcc5+ (which can also be used by clang-3.9+ with the
 new enhancements that are in the pipeline).

 This requires a WHOLESALE change in the settings, however, and needs to be
 done with care and finesse to have a hope of working.
