- The cut operation in the WAM implementation of Prolog does not in it
- self reduce the amount of used global stack. But a garbage collection
- does reclaim the space.
-
- so
- ... test,!,garbage_collect,test ...
-
- is a way (in SICStus) to just use X global stack space.
-
- (It is not always true. Undo, setarg .. etc can make it hard to
- reclaim everything.)
