434 help
435 Select this option, if you want to enable the kernel interface
436 to reduce the memory size of the system. This is accomplished
437 by allocating pages of memory and put them "on hold". This only
438 makes sense for a system running under VM where the unused pages
439 will be reused by VM for other guest systems. The interface
440 allows an external monitor to balance memory of many systems.
