Designing ELF modules

Why doesn't someone work to fix that desperately 1990's behavior? Other modern OSs can page kernel memory, and they're based on code from the 1970's :]

It's not a requirement to be able to swap out ANY kernel memory location (i.e. not the kernel text or static data sections), just stuff allocated through a particular API, perhaps. In later years we might be able to back vmalloc() as pageable memory and kmalloc() too with a flag - with the march towards HSA any device that needs a swapped-out page would go through the same process of causing an exception/interrupt via an IOMMU so it can be brought back in. Someone would just have to figure out the security implications of putting data in swappable memory - I think this would be classed as more a defensive programming technique than a kernel feature, though.
