> Didn't 16-bit Windows and classic Mac OS do something similar? I assume this is what `{Local,Global}{Lock,Unlock}` were for when combined with `{Local,Global}Alloc({L,G}MEM_MOVEABLE)` Similar idioms occasionally persist in modern code - e.g. when dealing with FFI in GCed languages (C#'s `fixed` statement pins memory in place.)
