I wonder if that old hack (deleting the file signalling there's no rush about writing stuff back to the disk anymore, although it's still your backing store) still works?
Probably not.
Why does it do this instead of just mallocing stuff, anyway? (Quick and dirty shared memory again?)
It needs to be able to remap (including temporarily unmap) the memory freely, not only share it among several processes.
I'm more interested in correctness than performance at the moment. As long as it WORKS, they can leave it running overnight for now...
Just to give you alternatives, an alternative to UML is to use a emulator such as qemu. Personally I prefer UML, but using an emulator eleminates the need of the user to even have Linux to start with as the same image also works on Windows.
