 * Test that pthread_key_create()
 *
 *  shall create a thread-specific data key visible to all threaads in the process.  Key values
 *  provided by pthread_key_create() are opaque objects used to locate thread-specific data.
 *  Although the same key value may be used by different threads, the values bound to the key
 *  by pthread_setspecific() are maintained on a per-thread basis and persist for the life of
 *  the calling thread.
 *
 * Steps:
 * 1. Define an array of keys
 * 2. Use pthread_key_create() and create those keys
 * 3. Verify that you can set and get specific values for those keys without errors.
