  +//
  +// - Test that when Put() and Get() fail, they have no effect
  +//
  +// - Test what happens when the buffer is empty or has size 1
  +//
  +// - Exhaustively test the state space of a small circular buffer (if it
  +// works for a buffer of size 5, it probably also works for 128 - but
  +// with size 5 it's easy to write a completely exhaustive test that
  +// verifies that the buffer implements all operations correctly in states
  +// with all combinations of (head, tail))
