  27 /* General notes:
  28  *
  29  * All structures are reference counted to allow reuse without duplication.
  30  * A *_copy operation will increase the reference count, while a *_free
  31  * operation will decrease the reference count and only actually release
  32  * the structures when the reference count drops to zero.
  33  *
  34  * Functions that return an isa structure will in general _destroy_
  35  * all argument isa structures (the obvious execption begin the _copy
  36  * functions).  A pointer passed to such a function may therefore
  37  * never be used after the function call.  If you want to keep a
  38  * reference to the old structure(s), use the appropriate _copy function.
