+This means that you can call scm_protect_object multiple times on an
+object and count on the object being protected until
+scm_unprotect_object has been call the same number of times.
+
+The functions also have better time complexity.
+
+Still, it is usually possible to structure the application in a way
+that you don't need to use these functions.  For example, if you use a
+protected standard Guile list to keep track of live objects rather
+than some custom data type, objects will die a natural death when they
+are no longer needed.
