  Keep track of the active buffer on output.  For the moment, panic if
  the device indicates that it wasn't able to write all the data in the
  buffer out.
  
  Ed Schouten doesn't like the idea of a panic here.  I think for
  production code, we need something better.  For right now, while we're
  trying to assess the impact of this issue, a panic is OK.  So complain
  to me, not him if this is hit.
