    sys/kern             tty.c 
  Log:
  Improve the expressiveness of ttyinfo (^T) when dealing with threads
  in slightly less usual states:
  
    If the thread is on a run queue, display "running" if the thread is
    actually running, otherwise, "runnable".
  
    If the thread is sleeping, and it's on a sleep queue, display the
    name of the queue, otherwise "unknown" -- previously, in this situation
    we would display "iowait".
  
    If the thread is waiting on a lock, display *lockname.
  
    If the thread is suspended, display "suspended" -- previously, in
    this situation we would display "iowait".
  
    If the thread is waiting for an interrupt, display "intrwait" --
    previously, in this situation we would display "iowait".
  
    If the thread is in a state not handled by the above, display
    "unknown" -- previously, we would print "iowait".
  
  Among other things, this avoids displaying "iowait" when the foreground
  process turns out to be suspended waiting for a debugger to properly
  attach.
