    If you're using -ck1 it may even be the autoswappiness. Try disabling that and
    setting a static value for swappiness. If it still exhibits the problem then
    it's probably a bug somewhere in staircase. While the overall design is
    finished (it doesn't really lend itself to tuning), surely there are bugs I
    haven't sorted out even though there are no serious bugs or stability issues
    that have come up. I'm auditing the code as we speak.
