One problem with Linux in low memory situations is that the OOM killer is a really blunt force instrument. It would be nice if it were a lot more configurable.

You can do it completely in userspace, that's the ultimate configurability.

  You can adjust pid scores in userspace or turn it off, there's literally nothing else you can do.

    You can monitor memory, swap usage, lots of things about each process and kill processes all from a userspace program.
