pthreads provides the clunky pthread_getspecific / pthread_setspecific
API.

However, it is worth noting that recent versions of GCC support a
__thread storage class, which provides efficient support for
thread-local variables.  IMO, for anything that is performance
sensitive, it is worth structuring the code so that this can be used.
See (info "(gcc)Thread-Local")
