  #limit=
    clears the mark if the new limit is before the current mark
    raises ArgumentError if specified limit exceeds capacity
    raises ArgumentError if specified limit is less than zero
    sets the buffer's limit to a valid value
    sets position to the new limit if the previous position is beyond the limit
    preserves position and mark if they're less than the new limit
  #position
