  * A stand-alone application that tests thread local storage (TLS) on the
  * current platform.  It is written to avoid locks and condition variables.
  * Since it is testing thread-specific stuff, it's good to use as little
  * *other* thread-specific stuff as possible for these tests.
  *
  * Note that this test hangs in pthread_join() on ARM QEMU.
