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.)
