; void* __fastcall__ em_mapclean (unsigned page);
; /* Unmap the current page from memory and map a new one. The function returns
; * a pointer to the location of the page in memory. This function differs from
; * em_map_page() in that it will discard the contents of the currently mapped
; * page, assuming that the page has not been modified or that the modifications
; * are no longer needed, if this leads to better performance. NOTE: This does
; * NOT mean that the contents of currently mapped page are always discarded!
