 - Add a witness check in exit1() if not done already.
   - Check should be in thread_exit().  witness_warn() will need tweaking
     since it freaks out if sched_lock is held.
-+ Split witness_lock() into witness_checkorder() and witness_lock().
-  + Tested
-+ Add a witness_defineorder() that adds an order between two locks at

 - Fix show witness output to use paging.
 - Add generic sleep queue code and move msleep() and cv's to use it??
 - Add a MTX_NEW flag to bypass the LO_INITIALIZED check.  Here be dragons.
