Comment (by anonymous):

 I believe the code is right. If you create a space optimized circular
 buffer of a particular capacity e.g. of 10 elements it's capacity should
 remain unchanged (unless it is changed explicitly). When you normally
 instantiate the space optimized buffer the allocated memory (internal
 capacity) is zero. As you fill the buffer with elements the internal
 capacity grows but upto 10 elements. When you insert more than 10 elements
 then the oldest elements get overwriten. (And vice versa if you remove the
 elemens from the buffer the allocated memory slowly decreases.)

 Hope this makes sense.

 Jan
