+/* --- @sod_teardown@ --- *
+ *
+ * Arguments:	@void *p@ = pointer to an instance to be torn down
+ *
+ * Returns:	Zero if the object is torn down; nonzero if it refused for
+ *		some reason.
+ *
+ * Use:		Invokes the instance's `teardown' method to release any held
+ *		resources.
+ *
+ *		If this function returns nonzero, then the object is still
+ *		active, and may still hold important resources.  This is not
+ *		intended to be a failure condition: failures in teardown are
+ *		usually unrecoverable (or very hard to recover from) and
+ *		should probably cause the program to abort.  A refusal, on
+ *		the other hand, means that the object is still live and
+ *		shouldn't be deallocated, but that this is a normal situation
+ *		and the caller shouldn't worry about it.
