    p.s. to everyone following along... this change is a precursor of things
    to come.  It's a BIG deal.   Make sure you have an up-to-date kernel 
    due to the recent TLS bug fix.

    The big deal here is that we are now using TLS (thread locale storage)
    in all binaries, even unthreaded ones.  That is, we are starting to use
    __thread for per-thread declarations like errno, whether the program
    is threaded or not. 

    This will allow us to normalize libc and *GREATLY* reduce the complexity
    of the thread libraries.  e.g. things like 'strtok' won't have to be
    avoided and won't have to be overridden by the thread library.  The libc
    version will 'just work'.
