How about if we do the non-wait-channel states in CAPS, and the wait
channels in small letters?  This should be pretty clearly visible...
This would even work with the cpu indicators (which I like).

We could even change the header to indicate this.  Thus you'd have
something like:
  PID USERNAME PRI NICE   SIZE   RES STATE/wchn TIME   WCPU    CPU COMMAND
