  Log:
  o Don't add a scope system thread's KSE to the list of available
    KSEs when it's thread exits; allow the GC handler to do that.
  
  o Make spinlock/spinlock critical regions.
  
  The following were submitted by davidxu
  
    o Alow thr_switch() to take a null mailbox argument.
  
    o Better protect cancellation checks.
  
    o Don't set KSE specific data when creating new KSEs; rely on the
      first upcall of the KSE to set it.
  
    o Add the ability to set the maximum concurrency level and do this
      automatically.  We should have a way to enable/disable this with
      some sort of tunable because some applications may not want this
      to be the default.
  
    o Hold the scheduling lock across thread switch calls.
  
    o If scheduling of a thread fails, make sure to remove it from the list
      of active threads.
  
    o Better protect accesses to a joining threads when the target thread is
      exited and detached.
  
    o Remove some macro definitions that are now provided by <sys/kse.h>.
  
    o Don't leave the library in threaded mode if creation of the initial
      KSE fails.
  
    o Wakeup idle KSEs when there are threads ready to run.
  
    o Maintain the number of threads active in the priority queue.
