It's an extension on C that NeXT uses.

The new paging algorithm will re-use pages from the original EXE
instead of swapping unchanged pages to the paging file, if the page
has never been written to.  Thus, when you're paging, performance is
slightly better also.  This new method also saves on the number of
disk writes required while paging out, and reserves some pages for
page tables, to reduce PT thrashing.  Overall, paging is much more
tolerable.
