Great Apple seems to fix the Vmem problem on Tiger, then gives you a real memory problem.

As for what Apple is doing--not much that I can see. I browse http://lists.apple.com/archives/java-dev/2005 almost daily, and "memory" just doesn't seem to be on their radar.

Sigh.

Anyway, I'll keep watching the memory use charts (I try to save them after each session).
