+ \section1 Garbage Collection
+
+ Qt Script objects may be garbage collected when they are no longer
+ referenced. There is no guarantee as to when automatic garbage
+ collection will take place.
+
+ The collectGarbage() function can be called to explicitly request
+ garbage collection.
+
+ The reportAdditionalMemoryCost() function can be called to indicate
+ that a Qt Script object occupies memory that isn't managed by the
+ scripting environment. Reporting the additional cost makes it more
+ likely that the garbage collector will be triggered. This can be
+ useful, for example, when many custom, native Qt Script objects are
+ allocated.
