  * interfaces simple, I did not want the caller to have to pass in a
  * memory buffer, but having libical pass out newly allocated memory
  * makes it difficult to de-allocate the memory.
  * 
  * The ring buffer in this scheme makes it possible for libical to pass
  * out references to memory which the caller does not own, and be able
  * to de-allocate the memory later. The ring allows libical to have
  * several buffers active simultaneously, which is handy when creating
  * string representations of components.
