Well, the memory leak (whatever it is) is down to about 50MB/day. That's still not going to work in a production environment, but it's slow enough that the demo can run for about 11 days (well, make it 10, it needs some ram available for actually interacting with users). It's also slow enough that the amount leaking disappears in the normal fluctuations of operation over time scales of hours so you have to look at the graph over half a day to see the general upward trend.

Anyway, Rosey was napping when I got up, so I'm waiting for her to wake up so we can do the shopping. Until then I'm thinking I'll test out my hypothesis from last night.
