I realize that such a feature in a GC of any language and type
must rely on the OS memory manager being able to free parts of
a previously allocated set of continuously positioned pages.
Does this depend on whether the used page is the first, last or
a page in the middle of the set of pages allocated in one call
to mmap.
I don't believe the GC frees half of allocated memory if there
are no references to the unreferenced point.
It would break c style strings I think.
