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.
