        automatic tss cleanup is not implemented by Boost.Threads as a
        reminder that user code is responsible for calling the necessary
        functions at the appropriate times (and for implementing an a
        tss_cleanup_implemented() function to eliminate the linker's
        missing symbol error).

        If Boost.Threads later implements automatic tss cleanup in cases
        where it currently doesn't (which is the plan), the duplicate
        symbol error will warn the user that their custom solution is no
        longer needed and can be removed.
