  SVN rev 203662 on 2010-02-08 14:08:52Z by attilio
  
  MC r202889, r202940:
  - Fix a race in sched_switch() of sched_4bsd.
    Block the td_lock when acquiring explicitly sched_lock in order to prevent
    races with other td_lock contenders.
  - Merge the ULE's internal function thread_block_switch() into the global
    thread_lock_block() and make the former semantic as the default for
    thread_lock_block().
  - Split out an invariant in order to have better checks.
