Hmmm,

AIUI it's something of a fake it until you make it approach. The application's address space is still just as fragmented, with all that means for the speed - and in extreme cases possibility - of heap allocations; but by mapping the application address space into hardware address space at a much more fine-grained level than a full memory page the amount of physical memory used is reduced.

While the article doesn't go into great depth about how it works, I assume it requires some level of collaboration between the application's heap allocator and the OS virtual memory drivers.
The paper is here[^]. The source is available here[^]. The paper claims to exceed the old Robson upper bound of O(n2/5(log n)3/5).

You could probably compile this as a native DLL and inject it into all running processes and market it online as a "Super Duper Memory Saver" for only $49.99 ... and it appears that the code would actually work. Hopefully nobody reading this actually does this.

Btw, the combination of algorithms they are presenting will probably have some uses outside of memory allocators... it looks useful for pattern matching too.
