Fwiw, its easy to replace the allocator used by lua, so if you found an
allocator that used mmap, and was better at returning memory for the
usage profile of a GCing interpreter like lua, that could be used.

On the other hand, maybe it doesn't matter  that the heap is large, the
pages will get swapped out, and if you never touch them, who cares?
