    v89 v90  
    148148   * If the FLAG_JOIN_DONE is not set, the K thread arrived first: the K thread blocks the K thread on the BLOCKED_JOIN condition, set the FLAG_KILL_DONE in the T thread, register the killer thread extended pointer in the T thread ''join_xp'' field, releases the ''join_lock'' in the T thread, and deschedules. It completes the T thread destruction as described in the detached case when it is unblocked by the J thread.
    149149 * The J thread test the FLAG_KILL_DONE in the T thread descriptor:
    150    * If the FLAG_KILL_DONE is set, the K thread arrived first and is blocked on the BLOCKED_JOIN condition: the J thread reset the BLOCKED_JOIN bit in the K thread, releases the "join_lock" in T thread, and returns.
     150   * If the FLAG_KILL_DONE is set, the K thread arrived first and is blocked on the BLOCKED_JOIN condition: the J thread unblocks the killer thread, reset the FLAF_KILL_DONE in the T thread, releases the "join_lock" in T thread, and returns.
    151151   * If the FLAG_KILL_DONE is not set, the J thread arrived first: the J thread register its extended pointer in the T thread "join_xp" field, set the FLAG_JOIN_DONE in the T thread, sets the BLOCKED_EXIT bit in the J thread, releases the "join_lock" in the T thread, and deschedules. It simply returns when it is unblocked by the K thread.
