That looks the same.

The total number from that report is about 706M.
My available memory has now jumped up from 640M to 1.5G after one of the
processes (which was reportedly using about 100M) finished.
I'll have to wait until the problem re-occurs and see what it looks like
then, but for now I used the numbers from "ps axu" to add up a real
total and then added the 706M to it and got within 300M of the memory
currently reported used by free.
What could account for a process actually using much more memory than is
reported by ps or top?
